Sent while pretending to care about my kid's birthday party. Seriously, my wife just came over and told me "It's time for the cake," but she doesn't understand how like literally totally busy I am. At work, they refer to me as the Philly Cheese Steakster. I am now walking out my backdoor, still typing. It's not that I don't hear my wife behind me, it's that I am just finishing up this one thing. She doesn't understand what it means to be multi-engaged. I am operating at an extremely high level and your email is super important to me. I will call you from my hotel later. My car starts up, purrs; I am typing.

Sent to you because holy crap, in addition to replying to your email, I also just totally said the funniest thing on Twitter. Here's how it happened: I'm here drinking coffee and I saw this older woman come in and she looked EXACTLY like Bruce Mau - weird, I know, but you understand. So, I closed my Scrivener window (remind me to tell you later about my screenplay - new idea: Foucault and Don Draper meet in a bar) and I opened up Twitterific and I just totally wrote about how crazy it was that this woman looks EXACTLY like Bruce Mau.
