I just got a text today from my 20 year old son saying he finally understood. He had a tough time in high school with bullying. He is now serving in the Air Force and planning out his future. His "friends" are still living at home, most with children of their own, no plans for education, etc. Makes you feel pretty good as a parent.
This is my second comment on this topic, but I think everyone agrees that discipline and values are important. Important enough to sometimes step on toes, even if those toes are related to you.
