Teenagers suck

And although you don't come out and say it, you allude to another BIG problem with families. They think the children are the most important. I've heard SO many single moms say "My CHILDREN are the most important thing in the world". This is wrong thinking, and probably one reason why they ARE single mothers. Their priorities were not in the right place right from the start. The most important thing is GOD and then your SPOUSE. Without them, there IS no family. Putting children on a pedestal only reassures them that what they say goes. They are essentially in charge of the family and that's wrong.
And then you end up with a 43-year-old living at home with his girlfriend and 14-year-old grandson on my dime and all the drama that goes with it.
