Darrin's Robot Knees 3.1

Two days after surgery and Darrin is doing great with his physical therapy.  He has not slept very much, but he can sleep after he comes home.  He attended his first group therapy this morning.  He walked all the way there, and all the way back, about 200 feet!

The board in the physical therapy room reads:

Don't Quit
When things go wrong, as they sometimes will,
When the road you're trudging seems uphill,
When the funds are low, and the debts are high,
And you want to smile, but you have to sigh,
When care is pressing you down a bit,
Rest if you must, but don't you quit!
