juvenile delinquent?

Yesterday should be a day to remember for Jacob. I say "should be" because he is only 5 and who knows how much he will remember later in life. So, he and his buddy were playing yesterday and decided it would be fun if they threw rocks at a neighbor's basement window (a house in the friends neighborhood). Golly gee, what happens when rocks are thrown at windows? Yep, they break. I think Jacob found that out. Not one of his better playtime ideas. Now we are in punishment/consequences mode around here. He's turned over his money to Mom and Dad, except for what's in his wallet -- it is nowhere to be found -- how convenient. He's now grounded from playing with his buddy, and gamecube and tv priveledges have been taken away as well. I hope a few life lessons will be learned from this.
