Kelly had Friday off, so I also took the day off. We had a great day making food and watching the British stage production of Oklahoma! Consequently, today Kelly is working, and so am I. I think of it as merely switching Friday and Saturday, which seems fair to me because I can avoid rush hour traffic and crowds on both days. Anyways, today I finished Chapter 4 of my dissertation. It turned out to be a 41 page, 35 MB monster, which explains why my laptop has been running so slow lately. Onwards to Chapter 5 (Gunflint and Strelley Pool Chert) and postdoc proposals next week!
