Old work colleague but we've kept in touch. Went to her wedding evening do back in September, I got them a lovely afternoon tea with voucher with champagne that cost circa £100 which is alot for me as I'm not that well off. Put the envelope on the gift table at the reception.
After the reception I hadn't heard anything for over a week so messaged "lovely reception, hope you enjoy the afternoon tea". The reply i got was "Yeah we are looking forward to it, we will have to get your address to send a thank you card". Not heard a word since.
I know people are busy, I know especially after a wedding (to be fair theirs was very casual) that people have stuff to do. But not even a text to say thanks, I had to message them and then nothing since. Is this rude?
