If you sent a child a birthday present would you expect any sort of thanks and if so what?
Didn't give it in person so that is out of the question. Not expecting a formal Thank you card but a quick phone call or even text would be nice. The closest thing to a Thanks is a status on the mum's Facebook saying "son had a lovely day, thanks for all the cards, gifts and the money, he's very happy" (not even tagged so people know it's there).
Am I being unreasonable in thinking that's a bit poor and almost worse than no thanks at all!
