I can't say I was so much nervous about meeting him (again), but nervous about saying something really dumb. But I don't even regret the Matt Bomer comment since his response was so damn good. :)
Awwww, that is a cute story. You try to help, and what do you get? ;) It seems like everyone who got to talk to Jamie at the con, felt like they had a special moment. Given the massive amount of people there and how many hours he spends at the con (conceivably 10am to 7pm) it's really impressive and tells you a lot about the man.
