Turns out I actually can eat lunch, read under a tree, come home on the bus, do miscellaneous home activities (like exchange heavy books), and still get back on campus in time for my afternoon classes.
Huh.
Pulled my first grad school project all-nighter last night. Because I’m stupid. I didn’t quite finish it (I wrote a predicate logic unification package, but not its extensions), but from the classroom buzz this morning everybody who did finish didn’t have the first part working, and I did. Maybe I’ll get Mickey Rooney Happy Fun Time Points.
