Are you smarter than a very smart 2nd grader?

We were at Dr Toni's office, waiting for her to be ready to see you. You had a ritual of always having a small bottle of orange juice, with a straw!, at her office. You had taken just a tiny sip, so that you could have most of it while you were talking with Dr Toni. You told me that you had drank 10% of the juice; I disagreed that you had drank no more than 5%. HMPH! You got up, walked over to the 2 guys also waiting & asked them to point to the 10% point on the bottle. They were smiling, a little uncomfortable at the odd questions. They didn't really answer so you asked, "You do know fractions... don't you?" They laughed & said that they probably didn't know them as well as they should. HMPH!! Just then a very sharp, well-dressed man walked in from the offices. You dashed right over to him & asked him to point to the 10% mark on the bottle. He gamely took the bottle, pointed out the halfway point (That's 50%), then half of that (makes 25%) and so on. From the look on your face, it was clear that you didn't agree with his assessment of how much you had drank & you asked, "Do you even know your fractions?" The man laughed & said he probably didn't know them as well as you did. Then he asked your name. You said, "It's Jamie. J. A. M. I. E. ... The I is silent." He said, "It's very nice to meet you, Jamie, with the silent I. I'm Dr Wentworth." LOL. I hadn't recognized him, but he was the owner/main psychologist at the clinic.
