Not sure why things happen the way they do..

Man that's a shame. I've lost a lot of close friends and family the last 15 years and I really think that there is no answer or reason. You just have to live life at its fullest and treat otheres right. Time heals all pain eventually,your friend will hurt for a long time but one day something good will happen for him and his children.

Sorry to hear about your friend. He and his family will be in our prayers. :angel
