Walking uphill into a built up area, I was suddenly aware of a sound of someone walking close behind me because the swish of their steps came just after the sound of my own boots hitting the footpath.
But I wasn’t sure whether the other footsteps were someone else, or the swish of my own over-trousers, so I deliberately slowed down to make the two sounds go out of sync, the swish sound kept going, apparently at the same speed, so still not entirely sure, I began to feel a sense of slight threat and annoyance at the alien footsteps invading my space!
Soon afterwards I realised that I wasn’t really slowing down, so I stopped and also looked around. There wasn’t anyone else, all I saw was a cardboard box on a doorstep that had a picture of a blue plastic wheelie bin on it.
So I had been feeling invaded – by my own trouser noise and this I found quite a comedy.
