Maybe he is embarrassed about his behavior? We can only hope. Or perhaps he is just waiting for you to cool off and hopefully forget about the FU. Yes, he did get his e-cig and didn't have to mow the lawn. sigh.... Sounds like what my hubby did before he finally kicked step-son out. Son would have a meltdown, hubby would get angry, but then try to pacify the situation by giving in to something (for the sake of myself and 10yo, to keep the peace) and it would start all over again later. We can hope that your son understands that his grand are serious about not putting up with that type of behavior. Maybe he gets it? We can hope. There is peace in knowing that you have tried, his grandparents tried, other relatives. He knows he is loved. Maybe one day (maybe soon?) he will get it.
