I was standing outside talking to my son in law yesterday, some young girl, probably late 20's, hung out the window and shouted "Look at that builders belly -Loose it". Not the first time I have been personally abused by young girls in the street either, its just something some people feel the need to do.
I take no notice, suggest you do the same, they are the ones with a problem not you.
Hope the rest of your day goes better!
