World of Mirrors

Opposite the station, there's a shop that sells tennis rackets that have had their strings replaced by mirrors.

Every time I stare at the tennis rackets, I imagine what else might be replaced by mirrors.

I imagine looking up at traffic lights, only to find that there is no red light, as it has been replaced by a mirror.

I imagine attempting to post a letter into a postbox, but finding I cannot, as there is a mirror there, stopping me.

I imagine breaking open a conker shell, and there will be a mirror there too.
