<human>: This happened about 2 hours ago. I am in a marching band and this weekend I was going to a parade, and I was super hyped about it. We get on the busses, and head down to the place where we had to perform. When we get close to it, the band got out of the busses and we started walking to the road where the parade is. While walking there, there was some random sandbag in the middle of the sidewalk and my friend, who is wearing a gigantic bass drum and can't see the sandbag, trips over it. He gets back up and we all had a laugh. Soon enough, instant karma! There was a weird increase of elevation on the sidewalk and I couldn't see it either, because I also had on a bass drum, and I tripped over it. It  tore a hole in my BRAND NEW jeans, and I got a big scrape. It really hurt to walk in the parade because we went so far. This probably isn't a major FU but just wanted to share it.
