Forget Myers Briggs

The best way to really get a handle on people's personalities is to be in a household with one bathroom. True personalities come out in the bathroom. Ashlin, for instance, wanders in to use the toilet while I was putting on makeup and instantly starts to fill my ears with information about her favorite foods, an episode of Mr. Dressup, the prevalence of grass in swimming pools and how much she likes the word butt.

When Taryn is in the bathroom, she is often quiet, and she could be in there for half and hour or more. She ponders. She slowly measures out the right amount of toilet paper. She makes up songs. She pulls off every towel from the towel racks and drops them on the floor.

Conor, meanwhile, screams bloody murder about the very idea of using the toilet, but he likes to flush the thing.
