Bring snippets of the unique lifestyle through the story. I remember that didn't feel doable in my first draft, but I kept trying and kept adding a little here and a little there through the following drafts. I particular tried to fit them in when the reader needed to know it, or a little bit before that. (And I held my cards until the last minute for other parts of what readers wanted to know. Never even explained the strange name of the protagonist until the beginning of the climax. lol) And, if you're thinking maybe my story doesn't have that unique a lifestyle, it's about stuffed animals learning how to live away from people. Since it's set in this world, there's a lot of details on how they've managed to hide that they are sentient beings from people for over well 100 years now.
I came up with a series of catch phrases for myself for each part of writing that I freaked out about. Fitting in the lifestyle here and there came under, "Breathe and keep writing. You'll get all info needed somewhere in the story sooner or later. This is a marathon, not a sprint." (Feel free to take it if it helps you're freak out. )
If I helped you, please critique my query -- The Comfort Ban.
Or the synopsis. (If you're in a particularly cheery mood, I'll accept a crit for both. Better yet, if you're in a foul mood, take it out on both. )
