Example #1 John Q wants Sam Smith to stop parking in front of his (John Q’s) house because there is no place for his daughter to park when she comes often to visit. John Q tells Sam Smith, “You better park somewhere else, because I wouldn’t want to see your windshield come up smashed.”, Or he says to Tom Thumb, “I know it is your boy hopping my fence to make a short cut. If he comes over one more time I would be careful if I were you walking home from the bus station, you never know what thugs might be around to mug a guy like you.”

Example #2 Trick Willy sees the BGF of his sister and says to her, “Going to go off to college in San Diego when you graduate, huh? I am almost done fixing this car up and I am going to start another project. I know how much you love this old GTO and you would look so fly in it at college. You help me with a video project, and maybe some stills, I will sell it to you for $1,200. With the paint and engine work alone it is worth $4,700. You don’t want to take that ”mom car” to campus, do you? Trick Willy says to Polly Purebread, “Your dad and mine use to play golf a long time ago, I was 12yr and you were like 10? Graduate school, that is great. I am doing well and just hate you ran out of scholarship money and can’t get a loan, if you would move in with me, be closer to the college, you can live rent free and I will spot you the cash for class, all I want is your company and maybe a little some’n some’n now and then.”
