Every year is the same we get together with DH DD x 2 take them out exchange presents - I buy them a big bag full around £50 each and DH gives them money in a card as well.
Last year I got a very cheap (£2) smelly set from wilkos and the year before a bar of chocolate, year before they "forgot" to buy something...which they thought was funny. Our DS usually gets a t shirt. They are 17 and 15.
This year we are taking them out cinema then meal so more money spent.
I have commented to DH and he tries to brush it off. It infuriates me
