Breet breet!

I had just changed into my extreme hot weather walking kit and was on the point of going out when I thought I heard a cricket or cicada chirruping somewhere in the house. Clearly a quick eviction was called for. I stood still to listen and immediately the chirruping stopped too. (This is typical cicada behaviour. Whenever they think you're looking for them, they shut up and concentrate on being invisible). A few more steps to check behind the door were accompanied by a few more chirrups from somewhere nearby. Stop by the door and immediately the chirruping stopped too. This pattern repeated a few more times. Walk, chirrup, stop, silence! Walk, chirrup, stop, silence!

Addidas hot weather track pants have an inner mesh or gauze layer to wick sweat away from the thighs. Worn inside-out by mistake, this mesh or gauze, swishing against itself when you walk, makes a noise exactly like a small cricket or cicada. And it stops when you stand still. You should try it sometime...
