Res ipsa loquitur

I am a strongly visual person and need concrete visual images to work with. So the idea of growíng someone up in my head doesn't really work for me.

I'm much more oriented to sound than to sight, and my visual images of fiction are usually kind of fragmentary. (This is even true of things I write myself.)

So in a book, as long as the writer gives me a slightly more mature behavior and/or speech pattern for the character, I'll accept that character as an adult. In a movie or TV show, I guess what happens is that I don't retain any coherent visual memory, just snippets, and I can replace those with snippets of older faces if I concentrante a little bit.

But I'll bet more people are visual like you than are auditory like me. I wonder how the rest of them handle this? Because I'm with you -- it would sort of wreck my enjoyment of a sex scene if I found I was picturing little Daniel Radcliffe in it.

I guess maybe the visual people are looking for images of adults to take his place in their heads, like liviapenn's Johnny Depp and miriam_heddy's Blaine Capatch. Or maybe that's what fanart is really for?
