Lev: By sprinkling, you mean not too intense, right?
Right. Traditional kiruv is not usually the correct approach here; because kids already have the knowledge of the Jewish world. If and when they do decide to come back, they can glide right back in to the way they were brought up, albeit with a lot more meaning and understanding this time around.
Having a DMC (sorry guys) over a game of pool is nice all the time, and coming to you for shabbos is nice every once in a while.
Oh, also: It helps if you smoke. Just saying. Knowing your sports is a close second.
