A fairly distant in-law relative of mine has children of a similar age. She's sent us Christmas presents for our DC. We barely see them - probably less than once a year on average. Our children don't need the presents, I seriously doubt hers do either. In the past, I have sent presents when hers arrive, and then have suggested when I saw her that we didn't do presents again as it's a bit of a waste of time (I have no idea what to get them, I have to get fairly generic "children of this age probably like this" things) and money (last year DS asked who "X and Y" were, he has no idea). I thought we had an agreement, but obviously not! My final straw is that I never get any kind of thank you, or even an acknowledgement they've arrived.
Bearing in mind the last day for Amazon super-saver delivery is tomorrow, do I buy them gifts this year or not? I will be sending a thank you after Christmas.
