As part of a committee in our very small village, there is one woman who is ALWAYS moaning and negative about everything. She spends most of her time shouting at one of her children and the rest of the time complaining. She also has a martyr thing going on and quite often threatens to walk out or stop being part of the group when things don't go the way she wants. I think she does have good intentions but she's also quite abrupt and is starting to rub people up the wrong way. Is there a way to manage behaviour like this does anyone think, or it it inevitable that she's never going to be a ray of sunshine?
