If it was fluttering in a hedge without a visible living thing or wind causing it to flutter I'd be terrified as well. Depending on what a carrier bag is in the UK. Here that would suggest a bag like a duffle bag you'd take on a plane or bus.
Oh those bags do blow around eaeily although some animals react to plastic bags. Cats often like that sound but hate aluminum foil sound. We have both. Those plaatic bags are great for small waste cans and for the crap and pee from litter box. Too many conplaints here so we have both here. We have tons of for life bags and I love the freezer ones. They work for hot food too. But still love having plastic bags for other purposes.
In the meantime scumbags who push the environmental crap on naive hippies dump chemtrails daily and these fools blame plastic pollution for all the crazy weather issues. This tic-tac toe in the sky isn’t normal but young people don’t know any better. Older people who deny this are in denial or brainwashed. Charging for the bags is a way these turds get more money from those they slowly kill by dumping the trails in the sky then adding gmo and nanotechnology to food to fund their genocide. People are paying psychopaths to kill them. Uh oh off topic again🤭
The scheme with the flimsy plastic bags failed completely - People immediately bought a few bags for life - It''s only on rare ocassions when I forget mine, I am forced to buy a more stronger plastic bag. That's enough on this topic 🤪
