Actions have consequences.
Read that. Read it again. Let it absorb slowly into your conscious.
We learn about cause & effect at a young age. Stick your fingers into a glass of water, they get wet. Run towards the street, and Mommy flips out and probably spanks you.
Gets a little more subtle as we get older, but not much. Don't study, don't pass the test. Miss the application deadline, go to your second-choice college. Have sex, get pregnant. Join the Navy, learn the joys of beauracracy.
Here's one some of my nearest & dearest are having a problem with lately:
Leave your wife, see your kids a lot less often.
Yeah, there are some custodial fathers out there. But not many. There are some parents out there with a true 50/50 custody arrangement. But not many. Standard visitation, as explained by my lawyer, is every other weekend, maybe one night during the week, & some school holidays plus a few weeks in the summer.
Rob gets the girls Friday mornings, gives them back to me Sunday evenings. (Four and a half hours till I pick them up again! Yay!)
He's complained to me a few times about only getting them three days a week, two of which he generally works. His boss told him he can have a job & support his kids, or he can stay at home with his kids and not have a job.
I told him, "You know I love you but you made your choices and there's not anything else I can do to help you."
Consequences, boys. Consequences.
