My Friend Peter, that sarcastic SOB

I truly am a shitty friend. My friend Peter died recently of complications from a pancreas transplant. Yeah you pretty much need one of those. Peter was a tremendous high school athlete and good looking dude. He and the boys used to come into the diner I worked at on Sunday mornings after hockey practice. Unfortunately I had eyes for another Peter in the crowd (big mistake - he wore Frye boots). We ran into each other again a few years later in a coed softball league and became good friends even though I was married to who would later be called "that asshole". But he was always there for me - he had had a kidney transplant a few years before that but was doing really well. Unfortunately all the drugs and diabetes took a toll on his body over time and he just couldn't fight the fight anymore. For me I feel terrible we weren't closer over the last few years since I got remarried and he hadn't seen the kid in while. No excuse really since we live pretty close by each other. My bad. I have to live with the guilt and that sucks.
