S.,
My advice is to "ignore him" when this happens. Walk away and display no reaction to him But "praise him" when he used "good" words and tell him "how nice it is to talk with him." This may take several days of "ignoring him" and asking "are you speaking to me?" He does it becsues it gets him lots of attention when he uses the "naughty" words. Attention is attendtion for kids (negative or positive does not matter to them.) Let me know if this works for him. (____@____.com)
