I was in a queue at the supermarket earlier today. Hardly a long queue, though a little busier than usual. When I got to the checkout, the lady who served me said, I'm sorry about your wait, to which I immediately replied, with faux indignation, but I've lost a stone!
She laughed, and I remarked that I was glad that she did - bless her, she said it had really cheered her up.
In an alternative, imaginary scenario which immediately started playing out in my mind, I said to her, well, you've got to enjoy the laughs and good cheer when you can get it, haven't you, because after yesterday's euphemistically-titled spending review, we're all well and truly fucked, aren't we?.
I may have then either trudged out of the shop with an aura of tragedy, or continued on to musing intently to my surely-now-less-than-appreciative audience about misery, alienation and death, depending which scenario seemed more entertaining in my mind's eye.
Probably the latter, because it would have annoyed the shoppers being held up further in the queue behind me. In the event though, I (thankfully) kept all this within the confines of my skull, and left her still in a moment of levity.
