(Although if you do happen to know which redshirt death on the first season of NextGen I might be, please do tell me. I'm unlikely to be familiar with it, but I'm sure to be fascinated. See also: which major US airport I am, which small ceramic Red Rose tea figurine, which type of party hat, etc. I don't want to have to go through the trouble of taking quizzes, so if you are harboring this sort of information, it would really save me a lot of time.)
It's amazing what associates with people. redbird, for example, associates with Lemon Zinger tea in my head, and I have seen papersky wear a shirt that is almost the color blue rysmiel associates with. But papersky, who properly ought to have a color blue in my head, has not; instead she has a fabric texture, a particular kind of woven linen-cotton blend. (I hasten to add that whatever other folks may think of Lemon Zinger, that blue, or that linen-cotton blend, I like them.)
Brains. A lot of trouble, but really quite entertaining when you get down to it.
