Mil and sil live abroad (Europe). Mil does most of the communicating between DH and the family who live near her (sil and her family)
A few years back when we had our 2nd child mil contacted DH and said the family were just buying for adults from now on...fine by us we understand that with 2 DC to buy for it was a stretch for some.
Fast forward to now...we bought sil's 3 kids presents and posted (were UK and it cost as much to post as we spent on presents!!!) And we've got a message from mil asking why we haven't sent sil a present too. She's now saying she never said there was a no adult gift agreement and we have to buy and send something to sil and her husband.
Aibu to say no...we agreed no adults.. and it would cost money we don't have to buy them presents and post, which probably wouldn't be there in time for Christmas now anyway!!!
