Having checked back to my original on-line chat with a colleague, I find I mis-quoted my own proverb! I should have said it was "Never trust a frowning rabbit".

I have now used both phrases in conversation, as the third time I used the "worried" phrase. But this time I got picked up on it, and I had to confess - much to their amusement. Even funnier - they thought that I'd used the phrase four or five times earlier in the week, when I know that I used it only twice!

Nice to know it had stuck in their mind. And here's a hint on successful use: Only use it in a group conversation. In group conversations, any individual is much less likely to ask about the new phrase, as they won't want to look ignorant in front of the others!

But in a 1:1 conversation, you may well get asked. Let them in on the joke if you get caught.
