Herb, my committee chair, is on sabbatical this semester. I've emailed him about my chapters, mostly to get his final approval on sending them out to the committee after Sam has already been over them. I haven't seen or had a conversation with Herb since December, and won't see him until the morning of my defense on Tuesday. Seemed like we should have some kind of meeting before my defense, so we just had a 5 minute phone conversation. Herb is a hands-off advisor indeed.
He said, "Well, it looks like a dissertation, it smells like a dissertation, so I think it's a dissertation." He doesn't think I'll have any problems. That's a relief.
For the last 3 days before my defense, I'm focusing on preparing the best presentation I can.
