We got down to 1 at home earlier this year. A few days after my youngest son turned 17 he decided he couldn't handle following any rules at home (like helping mow regularly when the lawn needed it), so he didn't come home from work one Saturday night. On Sunday he didn't want to come home, so the birthfather bought him a Greyhound ticket to his house (in another state) and my son has been up there since.
This was the son who said he was not going to do this! I don't think he fully thought it through, but it was in the back of his mind based on some things we have learned since then.
Several things annoy me here, but a significant part is that this son was learning to work hard and was really maturing through his work at a grocery store. He hasn't had any job since he went to the birthfather's house since it is harder for a 17 year old to work in that state and the birthfather doesn't expect anything out of him.
Ironically, he generally has no trouble helping out around the house up there.
He recently decided to join the Army. He scored very well on the test, but the Army (or at least that recruiter) is choking on his homeschool diploma here. It is as valid as any private school diploma (homeschools are private schools in Texas), but they are different in the state my son is living in and the Army is free to do whatever it feels like doing. He may have to take his GED, but he has to get school board approval in that state, something that is more difficult to obtain.
This son is likely to either do really well or really poorly in the service. If he is mentally committed he should do fine, but he can really rebel if he doesn't think he has to follow some rule. It will be interesting to see how this shakes out. We have given him our written permission to join whenever he wants. (That is needed since he is still under 18.)
While it is really annoying that my son has been enabled to leave home before he should have left, it is probably good that he is out. He was getting more violent and I am very concerned that he would have done something really wrong if he had remained here.
It also remains tough to keep a positive outlook for my youngest daughter to stay at home at 17, given that everyone else bailed early due to the ease of that in Texas, but I need to focus on the positive for her.
