I can plot the littering patterns based around school holidays. Industrial lager cans, full-size cigarette packets, and tobacco pouches are still there during school holidays, only occasional energy drinks. Once the children are back, then it's the motherlode – definite uptick in energy and other sugary drinks, crisp packets, sweet and chocolate wrappers, the (daily) huge Dairy Milk bar wrapper, service stations pasties and other sundries, and Capri Sun pouches. I'm not sure who snorts the aerosols. I'd mind less but a proportion of it is tossed into the trees where it's hard to retrieve. I only pick it up in the woods (two handfuls today and they've been back since Tuesday), the back entrance to the school is rubbish tip, you can chart their progress in discarded plastics. It's more than a bit depressing to be honest, like seeing someone under the age of sixty buying a copy of the Daily Mail (another thing I'd don't understand).
