He is 2.
I appreciate the receiving a card, I really do, but... this couple (who are/were friends are my MIL...now deceased) did the same thing on his birthday last year.
This year's is purple with pink butterflies... last year's I don't remember well but it was pink with a picture of a girl doing something birthday-like.
Cards not received last-minute so it wasn't like they thought they'd miss the post and had to send something they already had at home. Also money (or rather, lack of) not an issue here.
Is it odd thing for them to do? Am I being unreasonably ungrateful?
