Tell you what...I feel like a fogey around my stepchildren. I'm 31, and they are 16 and 13, both boys. I'm cool with their radio stations in the car, but I make em listen to bluegrass and old country-western swing minute for minute.
Really, you should see the way they run the house. They have been through their parents' divorce, and a nasty custody battle, and they are given ridiculous amounts of gulit-laden over-compensation. I am aghast.
Oldest has had every video game system I can name...currently hooked up via piggy-back on the living room tv is the X Box and PS2. Next to the main tv is a secondary tv, hooked up to the Game Cube. This is so one can either watch tv (satellite) while playing a game, or two can play different games side by side. They also have Game Boys.
If that weren't enough, they have no nighttime curfew. Well, not during the summer. Their dad gets up for work at 4 am and tells them to go to bed. I put my foot down recently about the electricity consumption when I got up in the middle of the night to pee and one kid had the tv on, Game Cube tv on, and the computer online simultaneously. It was sick.
