Okay, I went to the movies with a couple of my roomates. I was the first to walk into a row to sit down. I sit down and both of my roomates sit with an empty seat in between me and each other. The arrangement looked like this:

me-emptyseat-roomate#1-empty seat-roomate#2

I have noticed this before by watching other people, but it only happens with guys. I have an idea why this occurs, but I am curious if any of you have ever seen anything like this before? I could care less if my friends sit next to me.
