I really don't think life is about the I-could-have-beens. Life is only about the I-tried-to-do. I don't mind the failure but I can't imagine that I'd forgive myself if I didn't try.
We all have that burning question about what happens if we lose somebody we love especially if we lose them tragically. We wonder what fear was going on we wonder if we could have reached out and touched them held their hand looked in their eyes been there.
