I really get the hump when my friends send a general email/ facebook post instead of a card under the intention that they'd rather give the money to charity. the whole point of cards is to personally tell a friend that you are thinking of them this christmas and to keep in touch. I find its usually my friends who can't be bothered to send cards that op for the charity thing - in the process acting smug and superior to those selfish people who send cards! Id rather they didn't send any and not tell everyone how brilliant they are!
