Thanks for all of your comments guys, I appreciate them

also, thanks for the get well wishes.
I hope that my dad will be alrite. One thing that I didn't mention was that 10 days ago, he also had a pretty good sized heart attack, so they did angio plastiek (however you spell that) to clear his main artery and then they kept him in there until Wednesday to have the surgery.
I thought that getting out 2 days later was early, it sounds like a lot of you have had the same experiences.
