A friend asked if I could pick something up for her whilst shopping, which I did. it only cost around £3
She said that she would send tge money over to me. I did mention the item in a message the next day,and she said that she needs to pay me
Do I just let it go now? It's not so much tge amount, but the principle.
I could factor it in the next time we meet (for example, if I pay I could add it on, or take it off a future payment to her)
I am thinking its negligible, so to forget about it..I really hate things like this though, and they can add up!
