When I lived in the same town as my mom I had a job that was shift work, so my days off were on days that she worked. I was in my mid 20s. One day, on my day off, she had the nerve to call me and ask, "You're not doing anything today, why don't you go run X errand for me?" This involved driving to another town about 20 minutes away, picking up 1 or 2 items and then taking them to her while she was at work.
I quickly corrected her and said while it may be my day off I certainly did have things to do, and quite a few of them too!
