Who did I piss off?

Man. Irritating day on the bike. I left the house for work at 6:20 and I wasn't 300 yards fom the end of my driveway when I got a rear flat. I hoofed it home and changed tubes, and had to push it to get to work on time. I made it, but the thighs were smoking. After work I just planned to take it easy going home, and was right by the smelly water treatment plant on Gas House Pike when it went flat again. I pulled a big sliver of glass out of the tire this time. I also found that the spare tube was presta instead of the schraeder I usually run on the old school Fuji. I stopped by the Bicycle Escape (right on my route) and picked up a couple more spare tubes and tried to ride gingerly home, but flatted again in Libertytown. I could have changed it again, but I was beaten. I called the Mrs. to come and give me a lift the final three miles home. I think the rear tire is getting pretty thin (2 yars old for a weekly rider), so I'm going to change it out. But sheesh.
