Doing 20 minutes of guided relaxation to help switch off your brain: valuable.
Two minutes of dozing: lovely.
The sound of the cat throwing up his entire dinner (and then some) on the hallway carpet just outside the bedroom: inevitable, really.
Your half-asleep husband complaining and asking you when you are finally coming to bed and turning the lights off, while you are on your knees in the hallway cleaning cat puke out of the carpet: priceless.
Thank the gods for the ability to laugh at life. :)
