Sometimes a story will feature sections of bare dialogue. These are like overhearing a conversation, and you have to guess what is going on around them based on the content of their talk.
It's all right not to specify things in a story, but we need to be aware that very often, a reader will fill in what they don't see with defaults.
Defaults are culturally dependent. They can be influenced by regional expectations. In some regions, "of course you have a basement." In others, "of course you have central heat." Where I live, it's astonishing if your house is not bolted to its foundation (because houses will walk off their foundations in a major earthquake).
When you are thinking about what kind of room your characters are in, remember that rooms have idiosyncracies. Ask who decorated them. What were they intended for? We noticed that Paul has maps and a sword in his room. I have wall hangings and a dresser. Morgan has a gaming chair and a dusty exercise machine. Ask whether a room was deliberately decorated. Was it filled by someone who had time to fill it? Were they in a hurry in some way?
Characters don't always think about everything around them. What does a kitchen look like if your main character has no interest in cooking? Morgan talked about having a character like that and comparing her view of the kitchen to that of her boyfriend who cooks.
Why do people pay attention to particular things? How does that change depending on their circumstances?
LaShawn noted that it's fun to play with character blind spots, with things they don't notice. If you want a reader to notice something that the character doesn't, you can always lay out an array of important and unimportant items. Paul remarked that sometimes an author doesn't plan the array, just puts a bunch of stuff out there and then some of it proves to be useful later.
Morgan asked how much we all look at hotel rooms. Not much, unless we're first walking in or noticing something wrong or different. Paul noted that if you are in a hotel room overseas, the room can be more distinctly different. LaShawn told us she once stayed in an older building that used to be a Men's Club because she was in overflow of people into rooms for a conference. It was unique and bizarre, because the doors were eight feet high and even the wall fixtures were very high up. It's worth noting that a hotel is not the same as a b&b or a ryokan, etc.
Any change in height or angle can really change our perception of a place. Adult heights tend to come in a much smaller range than those of children, and particularly so within a single culture. Our expected range of heights is smaller than the actual range of heights.
How do people learn not to see things? We notice things when they are new, and after a while our eyes gloss over them. There is a difference between not being taught to see something, and being taught not to see something. In China Mieville's The City and The City, people are taught not to see things right in front of them. We are taught not to look at homeless people when we encounter them. A change of environment will cause us to see things we might not in our most familiar contexts. If we go to a foreign country we are trying to watch for new languages, etc. so we pay attention to more things.
LaShawn noted that not everyone is the same, with the same opinions and experiences. This means you will notice different things. Kate remarked that you can be a relative outsider to an area even when everyone in the area is native to it. People also don't necessarily fit into the roles they have been assigned. When characters struggle with expectations, that teaches readers more about expectations.
It's helpful to try to understand secondary characters.
Kate brought up unreliable narrators. You can't necessarily orient reliably based on what is in a character's head.
My own view is that there's no such thing as a reliable narrator.
You can use situational irony to point up the unreliability of a narrator.
Kate noted that it's a problem when everyone sounds the same.
It's good to get multiple people to look at and critique a story while you are writing it, because different people will notice different things. People who don't usually read genre will be able to tell you if the genre conventions you are using are opaque to outsiders.
If you are writing in someone else's universe, you need to be able to speak the language of the people who live there. Star Wars people need to know Poe Dameron's idiolect. LaShawn told us that Mary Robinette Kowal was able to fool a whole bunch of people into thinking she was Patrick Rothfuss because she had studied his tweet style.
It's a really good idea to pay attention to language. It's our tool for writing, but it's also largely unconscious. People can't actually tell you what they will say in a given social situation; only what they think they ought to say.
Make sure you do your research. Kate can't stand it when someone has girl scouts "be prepared." (The Boy Scouts motto) The person who hypothesized about the Yucatán meteorite was not Luis Alvarez, but his son.
Know what you don't know.
Morgan noted that spoken and written language are very different, and it helps to read your dialogue aloud.
LaShawn said she looks at some of her early short stories and wonders, "Why did I pick this name?" Morgan noted that you often have to come up with a reason why someone is named something a bit unusual for their culture.
The blind spots and things you don't notice will change over time. If you have a new baby, you will be on the lookout for baby emissions, and if you have a toddler you will look for small people so you don't trip on them.
If you see someone wearing spurs in a grocery store, (Kate did, and then later found herself post-riding in nearly the same situation) you can't really know the path someone took to get there. Be aware that there are things you can't know. Find experts to help you. Ask for the help of sensitivity readers, and pay them.
There isn't only one way for us to be who we are.
Thank you to everyone who participated in this discussion! I really enjoyed it.
