This happened to me as on many occasions, I had included gift cards for nephews and nieces but never got a thank you back or even a card from them, so I decided to ring them and ask if they had received the cards and the gifts I had sent, for security reasons more than anything else, and when they said yes they had, I just said, that is all I wanted to know, asked them how they were and rang off. After that, I never sent them a card or a gift again. If they haven't the courtesy to say thank you I am afraid they are now out of my life.
In many circumstances (I am 81 years old) I have stopped receiving cards and never knew why but a few months later found out that the people I had sent cards to had sadly died. I suppose that when we get to my age people are here one day and gone the next.
I am, from next year, starting to donate the money it costs me to buy cards to a charity.
Anyone else suffering from the tree pollen?
