My telepathic trays

I’ve discovered an amazing thing about my trays at work…they’re telepathic!   I have 2 trays on my desk, an in tray and an out tray, one at either end of my desk and it’s become clear to me that they automatically know what they are supposed to be for the person putting things down!  They can change their state of being from ‘in’ to ‘out’ or visa versa in the blink of an eye.   The practical upshot of this is that no matter which direction you approach my desk from, the nearest tray to you will always be the in tray (because everyone comes to dump stuff on my desk and rarely to take it away again).   It’s a miracle I tell you!   Don’t miss next week’s instalment - the miracle of the coffee making photocopier!  Marvel at the things that it can do…
