> Spot on, Lisi! I recently set up a stretch box for my 12-year-old who's
interested in getting into Android programming, and he quickly developed
the ugly habit of getting up in the middle of the night to watch YouTube
videos of other people playing Wii games... Currently he's on his summer
holiday so it isn't doing much harm, but in a few weeks he'll be back to
school and as a responsible parent I can't let this continue. Simply asking
him to stop doesn't have the desired effect, naturally. My wife is about an
inch away from banning the computer altogether, and I'm trying to find an
acceptable compromise to prevent that...
