I think that they definitely are not different shapes (take a look at the photo I posted and zoom in).
As for Dave...well, he was a bit antsy, lol. He came to the interview on roller blades and insisted that we conduct the interview outside on steps in the sunlight...nice atmosphere but a little hard to sit on the stairs, write, keep my papers from flying away, and hold a recorder at the same time.
When we eventually got kicked off the stairs by a doorman, we sat at a table at Starbucks and he couldn't sit still, lol I think at one point he almost knocked the table over!
But the fidgeting aside, he was very friendly and nice...and cute
I still have the interview on my recorder
