Have you ever heard somebody use the phrase 'I wished the ground would just open up and swallow me'? It's usually said by someone who has made a silly error in full view of others, or has another cause for a feeling of severe emnarrassment and they would like to simply disappear from sight.
Last turn we played 'Smites and Cannons'. The game was, as ever, accompanied by much hilarity. And then I made a slip and stopped on one of those Smites. Sure enough the ground did open up and swallow me. Not only swallowed but chewed - and according to others it sounded as though the ground enjoyed the experience far more than I did!
I must in future remember that other old saying about being careful what you wish for ...
