"Mother!" he screams, thankfully not followed by "fucker".
I tell him as calmly as I can that it seems like the computer is a distraction for him, and until such time as he brings his grades up, he won't get the computer back.
"You're making me angry!" snorts the son.
"Oh good!" say I.
So, I'm thinking that as a parent, I have a choice: I can intellectually spar with an 11-year-old boy, or be sleep-deprived and pooped and barfed on in the middle of the night.
I very much want to live to see the day when all of this translates into my son being the good citizen I know he can be. Still I wish I could skip his adolescence and go straight to the well-rounded adult with a nice wife and kids.
To the parents of the world, I feel your pain, every time I ruin my son's life.
