Op, any chance your Mom thinks you are not in a financial position for this? It's just so weird of her - unless you have asked her for financial favors.. as in - if she were paying for your visit, or she has bailed you out of any financial trouble? -sorry to ask, it just seems very weird of her
No. I think the excess of what she purchased just struck her, which I get, but the solution is not for their parents to get them no gifts. I decided to make light of it:
It's sweet that you brought them so much, but as their mom, if I don't get them a gift, they'll probably hold it against me in years to come.
