You have a thirteen year old son, Tiberius. If he needs it, Tiberius is subject to spanking as punishment. Tiberius cannot seem to get away from games. He has a Wii and an X-Box 360 as well as several games for his laptop. If he is not gaming on a system or the computer, he is on his DS or his phone with a game. If friends come over, they play video games. Tiberius does well in school and always gets his homework done. You have even used gaming as an incentive to do well in school. Tiberius has started to pull away from family time and family activities and chooses to play video games instead. Now that there is a break from school for the Holidays, Tiberius seems to be gaming non-stop.
It is time for the annual after Christmas trip to visit your grandmother and your aunts and uncles. The visit is only for a day. You will leave early in the morning, have your visit and return in the evening. You do this every year and Tiberius is aware of it. He typically likes the attention he gets from his great-grandmother and your aunts and uncles.
This year is different, Tiberius wants to stay home. He says he has almost completed a level in the new game he just got for Christmas and wants to finish it and he also says that "hanging out with the old people" is boring. You force the issue and tell Tiberius he has to go as it is a family tradition and it was planned and everyone is looking forward to it. To make sure Tiberius actually spends time with the family, you tell him to also leave his phone and DS at home.
Tiberius in in an awful mood on the car trip there. He is whining and complaining about wanting his games and being bored. His mood is no better upon arrival despite the fact that his great-grandmother and the aunts and uncles are doting on him. He is whiny and even verges on being rude. He remains sullen and withdrawn. You confront him privately and he tells you that he did not want to come see "your lame family" and he is bored and wants to play his games. You tell Tiberius that it is only for a day and the family loves him and enjoys his visits and he needs to stop being rude and withdrawn.
Tiberius does not improve his attitude and, in fact, when he opens his gift from your grandmother (a hand knitted sweater) he tells her he hates it and asks her when she is going to "get a clue" about what kids really like for gifts. Tiberius then announces to all that he hates being there and it is the most boring day of his life. Your grandmother is deeply hurt.
How do you deal with this situation?
