I live 3 hours away from db and sil so whenever it's their dc birthday and I send a card with money I never hear anything so I'm often wondering if they got it.
Dm lives near by and always tells me (when I ask) they got it because she saw it in the mantle piece but they wouldn't know she tell me this.
Is it not the norm now to say thank you anymore? They're very popular and social people, but due to the distance between us we only manage to see them a couple of times a year when we're down and to be fair they do host a nice day and go all out bbq and drinks wise.
I just find it weird I'm always wondering if nieces and nephews received their money? Some are old enough to text, some are smaller just wondering what your thoughts are?
