Wise words? The advice that I can't forget

From my nan telling me not to lick my finger when turning a page to dubious showering guidance, why do some things stick in our brain?

It's funny, the things that stick in your mind for ever. When I was little, my brother and I would usually go to our grandparents' house after school. We would be given our tea in front of the telly, which we would sit and watch while Grandad read the Express and Star and Nan read a magazine. I noticed that every time she turned a page, she licked her finger first. Deducing this was the kind of adult modus operandi I should be aiming for, I started doing the same thing. I went so far as to pick up magazines I couldn't even read properly, just to practice and perfect my finger-licking page-turning technique. Before long, my Nan saw me proudly in action.

Oh, don't do that, Ade," she said.
