On two occasions when I've sent cards to different friends, they've never even acknowledged it or said thank you. AIBU to find this really rude?
The first card I sent to a friend overseas to congratulate her on her engagement and was worried it had got lost in the post. I waited a few months to ask if she'd received it, as didn't want want to pester her. She replied to my message saying it had been received and thanks. Same thing happened with another friend where I sent a card to congratulate her on her new house. No acknowledgement so followed up on it after a few months.
Isn't it polite to acknowledge the effort I've gone to? Anyone else found the same?
