My condolences, R2D2 and the rest of you.
Growing up in a troublesome neighborhood in an even more troublesome country full with crime, wars, drugs and adolescents who are so obviously failing at their lives that you actually cringe as to what the country will be like in 10 year's time, I've had my share of deaths. Relatives I never knew were relatives died because of wars, other friends went to boot camp and never came back, and the 3rd group died because of reasons hardly known to me.
Best way to pass death, or to put it dramatically, survive the death of a close one, you just have to let it go. I've learnt that lesson when a friend of mine whom I knew since I was maybe 3 years old died from multiple stabbings, I just kinda learnt that being sad and depressed over it won't do anything. It won't bring him back, but he'll forever live in my memory.
Just my 5 pence
