In Autumn, the hedgerows are full of fat, red rosehips, which can be split open to reveal small, hairy seeds. These seeds can then be shoved down someone's shirt where they will itch like buggery, and cause bright scarlet rashes.
Precociously recounting this fact in a second-year biology class earned me the moniker "Nature Boy" from the indulgent teacher.
This was to be a short-lived glory however, as at the start of the every new school year, I'd be pinned to the ground and covered with rosehip seeds by a snarling mob chanting "NAY-CHUR BUH-MER" at me. When the rosehips ran out, they moved on to conkers.
Autumn is not my favourite season.
