A couple of lads had climbed up onto the roof of the bus shelter on the main road. They were about ten, maybe 12 years old at most. I realised as I passed that my mind had done those little assessments - are they safe? will it break? can they get down? - and moved on.
A moment later behind me, 'Get down, you vandals! Get off there!' - a voice in a suit. They scrammed, hopefully not accruing too much more resentment about the ridiculous intolerance of adults.
