So, through social connections I joined a committee of a village fete group. It was led by a very domineering woman who asked me to do sundry tasks, i.e. make posters and craft a few items. She was not happy with my suggestions and started telling me what she wanted and said that the committee favoured her work over mine. She kept telephoning me and I tried to stay polite. After a couple of very much her directed calls, I decided to withdraw my support by writing to the committee for a peaceful life. After this she began to telephone me on my landline, mobile, sent emails, and finally a letter by post. By this time, I was not answering her communications because I knew that she would be very rude and I was not prepared to put myself through that. My point: AIBU to think that sometimes you need to 'ghost' or 'stonewall' some people for your own peace and sanity when you know they will not take 'no' for an answer.
