Random Acts Of Kindness

This story was brought back to my attention a few days ago lol...but pretty much in my second year...I remember I was selling my textbook for like $100 or something like that and I met this dude at the mall. He gave me the money and I gave him the book and we went our separate ways...when I counted the money, I realized he had given me too much...$50 too much, he had given me an extra $50...the new bills were sticky and I guess he didn't notice. So I remember calling him back like 5 min after we exchanged books/money and I was like yeah...you kinda gave me too much money lol...so he came back and I gave him back the $50. It's funny cuz apparently we had a lot of mutual friends and I ended up meeting him again and officially through my other friend and we're still cool to this day. It's funny cuz I saw him the other day and he brought it up and he was like yeah man when that happened I told everybody cuz I couldn't believe it...lol...I can't believe he remembers something like that. Not to like toot my own horn...but when I saw it, I didn't hesitate, to me it wasn't even a decision, like he had already gave me $100+ for the textbook and I didn't think twice, my first instinct was oh, he gave me too much, I should call him. But yeah...I guess just little things like that where you don't see as a big deal, other people might. That's just a little reminder to me that...when you do things, don't expect anything in return, doing something good should be rewarding in itself. Thanks, gratification, appreciation and anything else is just a bonus.
