My special talent is similar to yours, Alison, except there are no nose-pickers involved. I seem to be able, at any given moment on my drive into work, to spot mad women applying their make-up whilst at the wheel. It's pretty bad when you spot them overtaking you and doing it but it's nothing short of terrifying when you look in your rearview mirror and see one of 'em roaring towards you. With both hands off the wheel, holding eyeliner or something. AND NOT LOOKING WHERE THEY ARE GOING! Ahem. Frightens the sh*t outta me every time.
