My children were brought up to thank people for presents they received. My daughter enjoyed writing notes but my son wasn't so keen, so he would ring and thank them.
Unfortunately, their cousins didn't do the same. We used to send a card with money inside (probably not the best idea but very common then) as they lived a long way away and never heard a dickey bird.
My DH has a son in Oz and he always sent money and a letter across for him and his subsequent children and once again nothing. To his ex-wife's credit, when his son was a little lad, she made him write thank you letters, but once he operated under his own steam it all stopped.
Anyway the upshot of this was my DH had enough and decided if they couldn't bother to acknowledge his gifts then he couldn't bother to send anymore and hasn't done for quite a few years now.

Well Labour’s “patriotism” didn’t last very long, did it? 🇬🇧
