I thought this was gonna be about you waking up singing. When I got my tonsils cut out I came to in full concert mode. I don't remember what I was singing, but it was loud and the nurse was trying to get me calmed down.
And you could have it all, my empire of dirt. I will let you down, I will make you hurt. Trent Reznor gave up the song to Johnny Cash. He totally owned it.
Good luck with your recovery. Get the rest you need, and push hard with it comes to PT. I lost some range of motion after my shoulder ordeal. I'm trying to get it back, but it's a slow process.
