Restlessness

I can't sleep.  It's not that I'm full of energy or have found a second wind.  It's not that I'm trying to stay up.  There isn't an amazing playoff game (scheduled way too late for kids to enjoy).  It's not like I'm reading a book that I just can't put down because I'm invested in figuring out what happens to the tertiary plot line.

I can't sleep because my wife is out of town.

I don't exactly understand why this is.  Maybe it is the imbalance in the bed, my side sinking just a skosh lower without the counterweight next to me.  Maybe it is the lack of background noise, her breathing gently drowning out the thoughts in my head.  Maybe it is just the uncertainty of what she is doing right now. 

Regardless, I'm looking forward to her flight landing tomorrow evening.  This way I'll be able to get a decent night's sleep.
