On the London Underground this morning I was watching a woman sat down, meticulously adjusting her hair in a small hand-held mirror.

This little bit back there; this bit brought forward etc… 

She was being very thorough and at one stage appeared to be struggling to get one part of her hair to go where she wanted it to.  This may be because the train was being jostled left and right vigorously, but it’s likely because gravity actually exists.

Suddenly she stopped and looked up, like a deer hearing a twig snap in the quiet wood or that realisation that you’ve probably left the iron on at home.  She was motionless, looking directly forward with intent and concern at no-one in particular.

“Atchoo!!”

She sneezed into her hand.  The hand she then re-applied to her hair.

I always thought sneezes were unpredictable and unintentional, but her (now ‘gravity defying’) hair would suggest otherwise.
