Man that sucks. I wish I could be more poetic but my first response was just a gasped "no", and I can't really think of anything more honest than that. I didn't know him that well but he was always friendly, we'd had a few conversations over the years and I remember him being an upbeat and funny guy. He was one of the people who often liked my posts here and he died so young. Maaaan that's just depressing. So long man, god bless, rest in peace and I'll miss you.
If anyone in his family should happen to see this, my condolences. I lost my father a year ago. I know what you're going through can't be easy, it's probably harder when it's unexpected. I'll say a prayer for him, it's all I can really do.
