Well, we'll agree to disagree, I personally went through something similar when I was a teen, it wasnt my best friend, but still lol... I was angry for a few months and I got over it after I got a new gf. I don;t know, I guess it depends on your personality, maybe some people arent as vindictive as most of you are lol. There's much worse things in life than dumb teenage love. I also think theres a HUGE transition you make when you go from high school to college, it's like entering a new world. You kind of tend to go: Wow, you mean there's a whole new life after high school that doesn't suck balls?
Also, the events that happened with his best friend/gf were like 3 years prior to him seeing him at the mall.... 3 years is a fucking long time to get over it in my opinion.
Again, I don't know. Most of you think it's unrealistic...that;s not my experience at all... but hey,I respect your opinions. I'll try to make him more bitter in the future lol
