I base my friends on things we have in common and that I like to be around. Hence most Iowa fans are insufferable so I don't like to be around them. Similar to people who are actively opposite of political beliefs, I don't want to hang around you and listen to your nonsense so I won't.So interesting.. I guess it all just depends on where everyone lives and luck / chance! I just hope people aren’t strictly basing their friends off of the college team they cheer for.
