Our mom always told us we had to be home BEFORE the street lights came on! That was always a little tricky but we did it. We weren't allowed to watch tv after school....we had to go outside and run around and then do our homework after dinner, before bath and bedtime. TV wasn't the all the time thing it is now.
I guess my son thought I was a bad mom but we never bought him one of those infernal game boys or other games as I see them being electronic heroin. He's 17 now and really enjoys a good book in his down time! YAY! (Of course there's the requisite IM'ing with friends but the boy knows how to hold a conversation)
