When the SA children come in saying 'bad' words I take them aside and explain that some words are not acceptable for the younger children and their parents don't like it when they come come saying 'crap' or 'weirdo' or whatever the word of the day is. After our talk it always stops. The older ones are trying to be big man on campus and use these 'big' words to show off. With the younger ones I just say "no potty mouth".
