if someones behavior was as infantile and pathetic as Johnsons was, i wouldn't look at them either. the message johnson should construe from that is he and his behavior aren't WORTH looking at. however, when your words and tone are as ineffectual as Philbins were then your whole presentation suffers.
i thought he mostly got off track when trying to teach chad the relative power of the infrequent f-bomb as opposed to continually using it. first of all, keep it simple. chad can only absorb so much instruction at once. state concisely what behavior was intolerable and then ask chad if he understands and intends to correct his behavior. assuming he says yes you then make clear the consequences of his failure to do so. end of story. back to business.
