I laid down to take a nap, earlier today. So, I layed on my right side, unbeknownst to me my cat, Tom, would join me for his daily nap, and proceed to lay with his butt near my face...anyway, I digress. When I woke up my left shoulder was hurting as if I had laid on my left side. What's up with that? I am wired weird in my old age. Go figure.
