Actually not a masked moan, but a genuine AIBU, so that I can make a decision!
I have been sending gifts to two different sets of children (amongst others) since they were born. On reaching early teen years, in both cases, any acknowledgement or thanks dried up.
Not one thank you, either at Christmas or birthday, or for housewarming presents. I would have no idea, in some instances, if the gifts had even arrived - if not for speaking with their mother.
This year, it has made me feel decidedly grumpy that, once again, I appear to be an endless gifthorse to young adults who see gifts as their right but cannot be bothered to say a simple thank you by card, email ....or even a text.
If I stop sending, it will certainly be perceived as an unpleasant stance on my part - so need to be quite sure that I am not being unreasonable to say "given that I never hear a basic "thank you", I won't be sending in the future".
Or have times changed so much that expecting a "thank you" is unreasonable, rather than just good manners?
