Dear Prudence,
I have a truck, and it is basically seen as an invitation to be a free moving company for people. I made an exception in my no-moving policy for the sister of my new girlfriend. She was 18 and moving out from one friend and in with another. I rearranged my work schedule to help her.
When I got to the apartment, she had barely begun packing. I got really annoyed and told her how rude and wasteful of my time it was. Even so, I was going to start getting the bigger items into the truck, when I heard her cussing me out under her breath. So I left. And then I texted my girlfriend about the incident. She sided with her sister and said that an 18-year-old adult is “basically a baby” and I was a jerk for abandoning her and breaking my promise.
We took a break after that but are trying again. My problem is that her sister continues to be snotty about the entire incident. She says I owe her money because she had to go rent a truck and had to miss work for the move. She manages to bring it up every time I am in her presence, and all my girlfriend can do is tell me to ignore her. It is getting really annoying. Should I clear the air or not?
