As a work-at-home dad, the vast majority of my summer has been a little like this:
I'm cloistered in my home office, which is rather close to the living room, scratching my bald head trying to concentrate on some programming issue while my son has his face pressed up against the glass portion of my office door, Wii remote in hand,
"Daddy, can you come play with me?"
"Sure buddy, as soon as I get off work this afternoon" / train of thought - completely derailed.
The kids started back to school, which makes the house eerily quiet aside from this similar little distraction, Penny - looking up at me as if to say, "I can Haz Kids to Play With?"
