balance PT again

Either the PT is already helping, or this is random variation, but I've felt steadier on my feet in the last couple of days. I also felt significantly, and reassuringly, steadier waiting for the trolley in the dark at Chestnut Hill Ave. today than a week ago. (Green line B, this is one of the stops that's not much more than a stripe of yellow paint between the tracks and the traffic lane.)

I had PT this afternoon, and this week the therapist had me doing some new exercises standing rather than sitting. I did some of them with my eyes closed, but am not sure it's prudent to do that here at home: I can use the edge of a counter to help me balance if necessary (instead of the barre in her office), but the office floor is flat, and a lot of the floor in this apartment isn't. I have a total of three new exercises, and will definitely be doing the other two sitting down.
