There are a group of men cutting down an overgrown hedge opposite me. All well and good but...…...They are shredding the "clippings" and creating quite a racket.They all have ear defenders but are not using them properly. The guy with the chainsaw has only one ear covered. The man on the shredder has both ears uncovered and the "labourer" has both ears covered from time to time. A fourth man looks like he is attempting to fly ,both ear defenders are" flipped "up off his ears.Being deaf myself I am sure they may be needing hearing aids before long.
