When I was about 20, I took a class with one SIL to make baskets. I made a basket and filled it with homemade jam and bread and gave it to a different SIL, not for any particular reason, it wasn’t Christmas or birthday, it was just because I was into that kind of thing at the time. Well, fast forward a few years, and she gifts me, for Christmas, the very basket that I had made and given to her! I think she had put something in it, maybe bath products or something. I didn’t care what was in it because the only thing I could see was that she had regifted what I had made for her and she clearly didn’t even remember that I was the one who had made it!
I didn’t say anything, just thanked her for the gift. But look at how many years later I still remember it.
yes, I was insulted at the time. It really highlights how little she regards me. Nothing in that relationship has improved unfortunately. She and my brother deserve each other.
