Maybe it's the curse of having teenagers, but when I hear "Rehab" I think Amy Winehouse. Here, though, "Rehab" is the place I go for physical therapy for post-op knee stuff. The only thing I'm in withdrawl from is walking.
Had a good experience there last week. I was sitting outside on a bench, waiting for my ride, when a woman wearing a bright lime green outfit, her head topped with a big puff of white hair, laboriously pushed a walker toward me. She sank gratefully onto the bench and pulled out a cigarette. She lit it, took a big draw from it, and said to me, "Pain sucks."
And there you have it.
