ha! I have the neighbour from hell. She is environmentally sensitive - as well as light and sound sensitive. I was out knocking rivets out of a frame one day she came out and told me to stop it was causing her to have an attack.
She has taken pictures of me working on cars to send to the city to prove I work on cars (its a hobby). She has even requested atht I not brush on paint as she is fume sensitive. Her husband was a mechanic - he had to give it up as he brought home smells on his clothes.
Meanwhile he was working on other folks cars in the neighbourhood for extra cash..hmm not sure how legal or hypocritical that was LOL.
I built a nine foot fence. It really helped. Out of sight out of mind.
