And this thread is a prime example on why parents shouldn't be afraid to spank kids these days. I realize it isn't always the right answer, but I got my ass kicked as a kid. I never got one I didn't deserve and probably deserved a few more than I got. But I have nothing but total respect for both of my parents. I know in the state of Iowa, it isn't child abuse unless it leaves a mark for 24 hours.
When I was in 5th or 6th grade, there was a local case on the news where a kid was getting disciplined by his parents via spanking. Well the kid didn't like that so he called the cops with child abuse charges. Well, that report came on when my brother and I were getting disciplined for breaking a fishing pole. He told us that if we ever called the cops on them with child abuse charges, there would be a reason for them by the time they got there. You know what, that thought never once crossed either my mind or my brothers.
TLDR, if you want respect from kids, you have to start with good strong discipline at a young age. Can't let them run wild up to junior high/high school, and then expect to reel them in.
