But first some background info: I work as a software engineer for a multinational company. I just graduated in the summer with a bachelors degree in computer science and this is my second job.
Today while returning from my girlfriend's house i stopped at McDonalds to eat something and the man taking my order was an old classmate. We were in the same class from the 1st to the 8 grade, and he always used to tease me and make fun of me, because i was smarter than him (I had the highest grades in my class). He was one of the people that made my life a hell for about 3 years.
Seeing him working there made me very happy somehow. It felt like some kind of justice was done. We recognized each other and talked for 2 minutes (while my order was ready).
I know it's not good to be happy that someone else didn't have as much success as you did, but it felt pretty good.
