Greeting Cards
I find it intensely annoying when I receive a card from friends and family with grown-up and adult children added.
When children are sufficiently grown-up, say over 16 they are more than capable of sending their own cards if they are able to do so.
In my case, these "children" are now in their 20's, 30's or even older !
None of them EVER contact me and some I have not even met. I find adding their names to my greeting card is excusive and irritating.
I know it is a general and traditional practice for particularly Mothers to do this, but I do wish they would realise that that their offspring are no longer children and should be left to send their own cards should they wish to do so.
