This was actually posted three hours before DH came home from work, which is the foundation of my long-term sleep deprivation; he's currently asleep in a chair in the living room, after an hour or so of telecommuting. It's arguable he never really comes home from work, some nights I wander out to fill my water glass at 3am and he's doing remote diagnostics on his servers, or deep in the middle of product research on new memory storage. He works until he hurts too much to think, takes his painkillers and nods off for a half hour or three, gets up, remembers a problem, and goes to work again... eats at weird hours, sometimes forgets to eat at all and gets mean and stupid and takes more painkillers and goes back to sleep.
Getting out to do chores in the morning is a complicated process; I have to fight my way to the bathroom through a phalanx of hungry cats and slow old dogs and then may find myself blocked because he's fallen asleep on the toilet again.
Oh, well, I guess I was overly optimistic when I thought marrying a man four years younger than me would keep me from being the one who did all the physical and demanding chores.
