Lost Thank You Messages

[Coppit]

My daughter X and me live in the west of England, my son and his daughter Y are in Kent. At Christmas I sent Y a generous cash gift but never had any thanks. X also sent her a gift - no message either. I had quiet word with my son who came back saying that Y says she had sent us cards, so there must be something wrong with our postal service, (What about hers?!).
The question is, are we, me and X right to feel a bit upset that no message has been received direct (not even by phone or email) from Y - or are we being unreasonable?

Oh Coppit, you've brought back some memories with your mention of lines. I had to write "I must not grin like a Cheshire cat when I am in a science lesson" 200 times. Teacher tore them up in front of me next morning. As for your question, I would feel unhappy about it too.
