I am so sorry.

I had a similar situation a few years ago. I go to a very very small school, it is K-12 and there are about 180 kids in the WHOLE school, so everyone knows everyone. Well, this guy that is a lot older than me, like 5 years, said hi to me. I just ignore him, and rolled my eyes because I thought he was just picking on me. I felt bad, but he was a really really good guy, but I never did say hi. That was on a friday, then on Saturday, he died, in a 4 wheeling accident.

I know it is a VERY different situation, when it is a good friend, but it still bothers me that I never took 3 seconds to say hi to matt.
