The daughter would have been stupid to give the bag to a charity shop in their area...and also, was it a bespoke designer bag, i.e. the only one of the kind to exist in the whole, wide, world? Isn't it nasty for a mother and daughter to gang up on another daughter, though? The word gift is self-explanatory - no strings attached. I rather think that they felt they were being cute. They weren't.
I agree that this was uncalled for by the mother & one of the daughters who was not the one getting the gift. Out of normal protocol totally.
Ganging up ( bullying ) was nasty on behalf of the mother.
