I used to be good friends with a work colleague. Then something happened (she cocked up, tried to remedy it and failed) and she threw me and a few others under the bus. I've never forgiven her. I moved job because of her. Never spoken since. It worked out ok for me but could have very seriously damaged my career.
Three years on, she has sent a personalised plea asking for money through one of the giving websites. Her eldest DD is horribly unwell and they are seeking treatment abroad.
Would you donate? DH says I'd be mad to do so. Given the circs (he saw the awful stress caused) and I should make a general donation to a relevant charity if I feel I should do something.
