DH has elderly parents a sister and neice who live 200 miles away where he is from.
DS was 6 this week. He got not so much as card from any of them. Same for my birthday a fortnight ago which is fine but I get a tad tiger mum about them ignoring my children. They sent DD a card a week late after seeing my message on FB about her birthday. It's the same every year.
Yet we always send our neice a card and present. On time.
And the rest of them for that matter although I only send cards to adults after they all ignored DHs 40th.
They never visit unless DH pays their train fayre (no car).
I don't expect a present to be sent as it can be expensive to post. But a card is not difficult.
I don't blame the parents as they are old and forget the dates. my SILis bizarre
