Well, ran into icouldhavelied at the bus stop, and she informs me that the May 3rd start date is for the six week classes. Full term classes start later. Oh, that explains all.... too bad I didn't know this before scheduling the maniacal travelling around this expected start date!
But as I'm going back to mom's, I realized this is a big blessing. I have time to relax, I have time to get my personal stuff done. I have time to clean my house. This is all good stuff.
So I took the bus into Squirrel Hill and walked back from there, stopping to symbollically smelling the flowers on the way. :)
