it can be a granny thing.
there is a woman near here, housebound now, certainly would never consider herself working class, small business, rotarians, tory etc.
she still puts banknotes in birthday cards for her GC.
i've told her not to, and that obvious hand-written cards tend to be torn open en route, because this behaviour is so well known.
makes no difference. guess it is an independence thing.
problem is, she may never know if it reaches its destination.
given usual behaviour of youngers not acknowledging cards/gifts, she has to ask if they received it, then they say yes, thanks, but they probably take no notice and can't really remember.
she has also been caught out by rogues, had to pay them over £100 just to go away. if she had told me, i could have helped, but pride meant didnt want to admit error.
