Hobbling Along

About three weeks ago I stumbled over a box in the basement and hit my left knee on a wooden stool.  Just as I was about recoved, about a week and a half ago, as I was climbing a carpeted stairway my right foot slipped and I fell on the left knee again I think bending it back further than it wanted to go.  This time there was swelling which has now gone down.  Oddly, there were no purple bruises either time.  I'm doing fairly well again although when I go up a step the right leg has to do the lifting.  Although I got to the mailbox a couple of times avoiding the icy spots and ran an errand for which I didn't have to leave the car, today is the first day I drove to McDonalds for coffee.  It was a test of what you can do while housebound and living alone.  A friend did grocery shop for me once and has offered to do more.  A phone and being able to go on line both help.  Also the attached garage.
