Dissertation Defense Protocol

If I have not already communicated the fact that I can be an awfully socially awkward person in certain contexts, let me do so now. I dread the odd social gathering at someone's house, unless I know most of the people who are going to be there, and even then, it can be cause for some anxiety. We're talking non-academic, even. So this is not just the pressure of networking. Oh no. It's not being able to answer a query from a person I don't know that runs like this, "Hey, you know that cake you brought? Are we going to eat it or what? Can I cut it since you're busy breastfeeding?" with an honest, "I was waiting until everyone--namely me--was finished eating, and I'd prefer to cut it, but thank you for your offer!" instead of muttering a weak, "okay" and then brooding about it for the rest of the party. . .er. . . weekend. It's deciding not to go to the shower at all because two were scheduled for the same day and you RSVP'd to the one given for the person you knew well, but not as well. I take comfort in my committee chair's admission that there are times that he has entered a home for a gathering and proceeded straight through and right out the back door. That's so me. So what am I worried about with the upcoming dissertation defense? Refreshments. Yup, you read that correctly. Because I heard waaay back--and again today--that the defendee (person on the hot seat) usually brings snacks or breakfast or something in hopes that the committee members are too charmed by the offering--or too afraid of crumbs escaping their mouths--to ask any difficult questions. Or as a courtesy, maybe. That was all vague. Anyway, it's been months since I've had any meaningful face-to-face interaction with my committee chair department head, and while I have asked a couple of times in meaningful ways what is expected of me, he simply will not say "some koolaid and a tray of brownies." So I'm in agonies over which snack would be too childish, the politics of pastries, what about the vegetarian (and what are his reasons for being vegetarian--do they preclude icing?), would it seem like a bribe--and a weak one at that, is it rude to come empty handed? (Except for the dissertation--there is that. . .) And that is my primary source of anxiety. What snack (if any) to bring, and how my choice of snack reflects on me. Literacy-chic, you are an idiot.
