No, I wouldn't, unless a rave of 300 suddenly appeared over the garden fence.
I hate snitchers and curtain twitchers. In the early covid days, we had reports on our community FB page of people saying they had seen neighbours going out for more than one exercise walk a day and other similarly shocking 'crimes'.
Yes. I hear there's a whole coach load coming down the A23 from West London this very afternoon. I think they should be stopped and turned back, and any business they were going to be up to down here left unfulfilled with the consequences that brings.
6 no, 7 no, 8 no - however, is there a cut off point when common sense goes out of the window and civil responsibility starts (on the part of the attendees, not the potential reporters)...
An exception would be the neighbour who burns their rubbish in their back garden. I would only have to suspect they had a mate round before I rang the police, just in case.
