So I have a very good friend that wanted a group of us to volunteer for her favorite charity as a present to her for her birthday. I said yes but completely forgot the day which she told me she signed us up for. She asked about a month ago. A few weeks ago, I got approached to work for that same evening for a catering company. It’s a ton of money for super easy work. I said yes to that, because I did forgot that we were supposed to volunteer. I don’t want to volunteer and need to the money right now. Am I an asshole for telling my friend that I don’t want to volunteer?
