So, a few weeks of battling for more than 4 hours of sleep a night and being uncomfortable 24 hours a day has me feeling sorry for the people that have to be around me.
Sorry that I can't play in the rough-and-tumble way that you like so much. Little sibling makes crawling around, falling to the floor and any kind of bending over really hard. Sometimes, I am moved by how happy even my smallest attempts at playing with you "like we used to" make you. Sorry I can't do that more.
Sorry because I can't promised a bettering of the situation for another... oh... 15 years or so.
