Hi, Lynne! My entrance into pillarhood is kind of shaky. It's really slow going(i mean that literally!) I'm two days out of the hospital and my knee is still pretty painful. I "zip" around the house with the aid of a walker and I have a nurse and a PTer(physical therapist) coming to see me. Lynne, Pet Talk people are the greatest! I have about 80 e-mails that were sent to the hospital from PTers all over! That made being in the hospital tolerable!
