Well we've just moved to a new home in Wandsworth. It's a basement flat, and it has a nice area in front of it (to park the car, and also stairs to the entrance). I had been picking up paper wraps and other rubbish that 'misteriously' appeared, but yesterday I understood where they came from, as I saw a bunch of kids (around 9-10) hanging out in my front door, eating sweets and even staring trhough the windows. I know they're only children, but I felt stalked (OK, not stalked, but you know what I mean...) for having them SO CLOSE. Is there anything I can do to prevent them from coming? Should I yell I them (first impulse), try to explain them calmly why I don't want them there, look for their parents? What'd you do?
