Just found out my childhood best friend, the kid who i grew up with passed away a couple of hours ago. Although we didn't hang around anymore (people, friends change through time) i still feel like shit.
Sorry to hear that man...
Something like that happenend to me also, almost 10 years ago.
I also lost one of my best friends because of a stupid car accident involving a retarded driver.
I can't describe the feeling.
My advice - just cherish his memory and remember him for the friend he was when you were hanging around.
