My mother has, several times, given me things and then wanted them back again.
A year or so ago, she gave me 5 or 6 Bossons (plaster heads that you display on a the wall, very popular 50 years ago but of no particular value).
Anyway, I put them up but decided I didn't want them and took them to the charity shop.
Now my mum wants them back.
But I don't want to tell her what I've done, as she'll be very upset. So I tell her that they're in the back of a cupboard.
Bear in mind I am 65 and my mother is 92. So I know how ridiculous this is.
Bit aibu to think that when you give something to someone they can do what they like with it?
