Last year I was plagued with punk kids playing ball, each time kicking or hitting it over the fence into my garden and banging on the door demanding it back; I vowed never again to answer the door nor return the ball(s). It has started early this year; a week ago I found a football in my garden - I trashed it. This evening in the sub-zero moonlight they were at it again. Morons.
After a period of doorbell ringing and front-door banging (without me answering), I looked out to see them climbing the fence in a vain attempt (in the dark) to locate a shoe which had somehow come over the fence. I shouted to get off the fence and (to their protestations) that it was their fault. I called the cops. Nearly two hours later the kids have gone and the cops haven't shown up. This Spring and Summer may not be anything to look forward to.
