Be Careful What You Wish For

So I was pottering about doing some tidying up and thinking to myself: 'I must stop in a minute and come up with a good example of the problems with my shoulder for the hospital appointment tomorrow'.

Then I tossed a sock onto the bed from about a foot away - cue bolt of pain coursing from shoulder to wrist, doubling me over, and the air turning blue for several minutes,

That'll do, I guess, but do be careful what you wish for!
