Favorite color, book, movie, etc.
I arbitrarily decided green is my favorite color just so I could answer icebreakers without looking like a personality-less weirdo. But really, I don't care and don't really understand having a "favorite".
Books, movies, other medias, I understand a bit more but still don't have any of my own. I rarely re-read or re-watch anything. And the things I do re-watch (mostly Halloween or Christmas season stuff) aren't my favorite overall, just for the applicable season. I can't recall the last book I re-read.
