I go out of my way to avoid people that used to be my friends.
When I visit my parents in the (small, Southern) town in which I grow up, I actively avoid seeing any of the people that were my friends in high school. If I happen to see someone I knew while I'm out in public, I will quickly turn around and walk in the other direction to avoid talking to them. I have even ducked behind a store display to hide from people.
They just all seem to have become huge losers, and I have nothing in common with them anymore and no desire to make small talk with them.
If I can't avoid one of these encounters, I am immediately irritated about it; these people are invariably frustratingly moronic. I can't believe that I ever had anything in common with them, and I am embarrassed about it.
IIN?
