We regularly exchange Christmas gifts for the children of another family that we are very close to. We've never discussed how much we spend but I usually aim for £15-£20 per child and have got the impression they do the same. We each have 3 DC.
This year I have done the same as usual but they have given our children a voucher for an experience day worth well over £100. I'm quite embarrassed by this generosity but not sure what to do, other than say thank you.
I don't want our exchange of gifts to increase to this level so should I say something or just offer a normal thank you and effectively just ignore it?
