I am assuming this is part of Italian-American culture. Maybe my poor Irish family just never could afford them.
That would be a correct assumption, since the OP said it in her initial post, and only you know about your own family's resources.
I sympathize with the OP. I can see how her mom's reaction was hurtful and unkind. If she wants to regift her favor it's perfectly within her right, whether or not we, strangers on e-hell, come from backgrounds where this favor gifting is typical. It's typical in my culture as well, but that's not relevant to the thread.
What's bothersome about the mother's actions is that she's insulting OP's gifts and broadcasting her intent to regift. Couldn't she have just regifted without alerting the OP to it? She doesn't seem to care about OP's feelings, in this regard. I don't think OP is being too sensitive about this. How would any of us feel if someone else regifted something either in our presence or told us about it?
My advice for the OP is this: you can't change your mom, but you can accept the reality that she is who she is, and gift accordingly. Whether that means you give her the same thing, something customized with her name on it
, or nothing at all, you do you. Work through your feelings here and with your loved ones and accept your mother for who she is, and limit her ability to hurt you, if you can. That may mean limiting discussions like this in the future. Less to criticize.
