Hoppers

The ohno-second. - Definition: Like the nano-second, this moment is exceptionally brief but it describes the moment when you realise that you have just made a big mistake. Like the split second between noticing that you have accidentally clicked "reply all" and the moment your finger actually hits the send button on that overly amorous reply to that email from Serena in accounts. But then it is too late to stop your finger mid-motion and off the mail goes.
But what if you had the power to hop back and not make that mistake?
