Time and time again, you'd be amazed at how I'd leave a smudge of toothpaste on the left side of my face. I'd ask where it was and try furtively to remove it, and you'd lick a finger and wipe it off instead. I blame this on the fact that I'm a right-hander who holds the toothbrush in my left hand.

Only you and my mum ever notice my careless trait.
