Ah, the power of two. There's nothing quite like it. Especially when it comes to paying utility bills, parenting, cooking elaborate meals, purchasing a grown-up bed, jumping rope and lifting heavy machinery. The world favours pairs. Who wants to waste the wood building an ark for singletons?

The year most of my high school friends and I got our driver's permits, the coolest thing one could do was stand outside after school and twirl one's car keys like a lifeguard whistle. That jingling sound meant freedom and power.

If I go into a sandwich shop or anywhere that features 'Today's specials' on a chalkboard more than 10 feet away, I have to ask for a printed menu. I smile at people I don't know on the street and ignore those I do. When at home, I often find myself grabbing my 'back-up' glasses to search for the better-loved pair I have left on top of my dresser.

My grandmother was a kind of Scarsdale, New York, society woman, best known in her day as the author of the 1959 book 'Growing Your Own Way: An Informal Guide for Teen-Agers' - this despite being a person whose parenting style made Joan Crawford's wire hangers look like pool noodles.

My mother is a special education teacher but also an artist, and my father an advertising executive. They are about as wacky as you can get without being alcoholics.
