I know this sounds weird, but when I see or am talking to anyone on these boards, I sort of picture them looking like the person in their picture for some reason...as long as it's a human. Even when someone changes their pic, I then identify them as the new pic. That's why some of the people that have girls, actresses, etc. for a pic, I thought were girls at first. Weird, huh?
I don't think it's weird at all. People's avatar is always somewhat of an extension of who they are and what they are like. Sometimes it is more literal and sometimes not at all, but it is rarely completely randomly selected in what I have learned.
