Why are some people stuck on the past?

Anonymous
I had a social gathering last week and it turned out a fiasco.

Someone I haven't seen since our HS graduation (now we're nearly 25) showed up. I know we weren't friends and I'm the least person she wanted to see and I'm aware she moved to a different city because of that.

Anyways I tried chatting with her and start all over, pretend to not know her very well... pretend to be a long time acquaintance. It didn't go well. She kept bringing back things from the past and at one point I had enough and said ''That was HS, I really thought you were past that already, I thought we could start all over again as friends''.

Suddenly she threw a drink in my clothes. That got me upset, I panicked and my old habit appeared. I threw a large bowl of cold tomate sauce in return and said Butterpants (her old nickname). Someone had to separated before she got more crazy.

Don't get me wrong... I felt bad at first but she got annoying. I was trying to be nice by starting all over, like the way you meet someone for the first time.
