Welcome Home!!! Glad the surgery went well, it'll feel better in a couple of days.
Basic rule of thumb: scheduled surgery almost NEVER goes off on time. Somone else's pesky gallbladder acts up or their dreaded appendix bursts, you know, stuff that pushes back the fun stuff, like fixing bones, etc.
They work hard, but their's always something that crops up that pushes things out!
Feel better!
