There are lots of things that are mixed up for those of us who are left handed. I have thought of another one.
I had a shot at the doctor's on Friday on my left arm. Yesterday, I barely could hold a piece of paper with my left hand without my arm hurting. Today, it still hurts.
I have a feeling that usually shots go in the arm that isn't used - I will remember this next time - and ask for my right arm to be shot up!
