It’s often pointless to confront these types of behaviors. Not like people would change it.

I just thought of other weirdness related to gifts. My sister in law has some insecurities, which results in her taking casual comments as insults or attacks. Years ago my brother brought something for my sister in law from overseas travels. She was showing it to me and I commented “what a nice thing it’s so cool I really love it”, her reaction was to jump and angrily say to me “well I understand you like it but my husband brought it to ME and it’s mine”. Dang. When did I say I want it?
