I once went to a professional soccer match and almost slit my own wrists.
I went to a match in London a few years back. We were about 30 minutes late to our seats and we got the nastiest looks from the fans. I think we offended them by being late. We left early so we could avoid the riots that ended up happening after the match. What a boring waste of time.
I felt the same way at Greatful Dead concerts (I've seen four). I would just go outside and party with the rest of the travelling carnival. Why do I bring it up? The World Cup is the same, except on a much larger scale.
