I wonder if I'm over reacting.
At Christmas I sent short letters in some cards to long time friends some from my school days, others from work (many long distance, some not seen for years but we always send a Christmas note and birthday cards.)
I had to explain the year had been hard as DH had been diagnosed with cancer. (So far he's in the clear but it's early days.)
Two friends have ignored my letter completely. No reply from them at all.
One sent a text saying sorry (I regarded her as the one who might at least phone me.)
One phoned me up the day they got the letter.
Another sent a get well card and letter to DH immediately.
Of the ones who have done nothing, would you drop them? No more birthday or Christmas cards.
It I'd had that news from them, I'd have sent a little card just saying sorry.
