"Hi, honey, how was your day?"
"Oh, fine, dear, the usual. I *did* help a frail older man unwedge a case of diet coke. The poor doddering old fool, was trying to bend over from the waist and pry the wedged case of diet coke with his fingernails.
"He seemed grateful."
I *was* appreciative, actually.
Neither my eyes nor my legs work terribly well, and crouching, which was what was needed, isn't really something I can do anymore.
I thanked him, finished shopping, and went home and had a good cry.
