I have mixed feelings about waiting rooms. Sure, I would like to be in and out as soon as possible, but the more efficient the office, the less time I have with my subject. I only had a few minutes with this person before I was called away.

I think you captured a lot in your short time with this person, a personality clearly comes through.
