The dangers of coming late to the conversation:
Coworker: Aww, you're a total dork.
Me: I know! I'm such a nerd.
New guy, walking by: Whoa, wait. You are definitely not a nerd. I know nerds, and you are not a nerd.
Coworker (to me): Tell him about your vacation.
Me, getting more and more excited: I'm going to LA to the Paley Festival, where I get to hear the cast and producers of some shows talk about behind the scenes stuff, and I'm going to a show taping, and I'm getting a tour of a digital animation studio, and doing other stuff, and then I'm going to write about some of it on the web.
New guy: Wow, you're a nerd.
