Sometimes the vagaries or felicities of language provoke or entertain. English can be rich in misunderstanding or misapplication. I blame my interest in this on the radio comedies I listened to when I was young, such as The Goon Show, Round the Horne and I'm Sorry I'll Read That Again.
The current use of the word "alarmed" and its ubiquity tickle my perverse sense of humour. I saw this on my way home this evening at Stratford station. Be careful, should you empty a machine of cash, the results could be distressing.
