My husband had a successful, easy knee surgery, and we were in and out in five hours. I was only waiting in the visitor's area for about an hour and 1/2 by myself. The other hours I was with my husband in pre or post surgery. During the hour and 1/2, I finished the next to last Sookie Stackhouse novel, "From Dead to Worse". It helped pass the time well and wasn't too hard on the brain.
Thanks everyone for your well wishes on the surgery! :)
