I know how you feel. I also have friends that have left us that were very young. (Damn! Now I'm crying) I think that it would be better in you go to his buriel or funeral. I could not bare go to the buriel of my last friend but I do regret it. And as you say, it was so sudden and it could happen to anyone. Even if your "worse enemy" dies, you would feel sorry for not gettling along with that person. That is why everyone should treat everybody as firends. All are loved ones. But it is damn hard to loose friends. R.I.P. to your friends.
