Just don't speak to the old bat! simples!
That's what we are going to do. (Mind you, she is not old. She is younger than us but I think she is 'daddies princess' who stamps her feet and gets her own way.) we tried to be polite but there is just no reasoning with some people so we are just going to stop them before they get chance speak next time. We get very stressed by the confrontation. Eventhough we handle it well when we are face to face but behind closed doors become a quivering jelly! I am determined this time to carry on and she is not going to stop me going about my business worrying i might see her.
