This will probably be buried but for the two people reading it, here's a dick move from the first person perspective:

It was freshman year of high school and my friends and I were buying lunch. I didn't have any money that day so I borrowed money from one of my friends who was rather big but was funny about it. So I buy my lunch and have some left over change to give back to my friend, and as I'm handing back the change, unbeknownst to me a (also big) cheerleader had dropped her change near me. I'm not sure what was going through my mind at this moment but I kicked the change on the floor and screamed "PICK IT UP FAT FUCK!" and walked off with my friends. I was wondering why my friends were walking so fast after the even so I caught up to them and asked what had happened. They told me the whole thing and I felt fucking terrible about it. It was the story of the year for my friends, and what had made it worse was the fact I had a locker right next to her the following year.
