Well I dunno if this is only snakes or not but here goes.
My worst loss was my dad, he died the February before I graduated high school. It hit me very much by surprise. We had, in the past 4 years been enemies. But he was trying hard to repair mistakes made when I was a child. I never let him, and he died one night with all we had between us unforgiven. I loved him, but I was young and never said it. When I graduated that year I did so in a way I hoped he woulod have found funny.
Children are stupid, I know I was. I lost him, and I tink of it every day.
