Not so long ago I was carrying some heavy shopping bags through town. I had on a pair of draw-string trousers which happened to undo and fall down around my ankles. I couldn't just drop the bags as they contained some delicate items and I felt exposed for longer than I would have liked. If only I had been wearing a nicer pair of knickers. I recieved some amused stares from other shoppers. How I blushed.
