My youngest was my *test*. My other two were fairly easy (oldest was busy, but not all that ornery). My youngest made me pull my hair out, and at HOME we had some real knock down drag outs to put it mildly.
He also had some moments in school that were difficult to say the least. There were times I really questioned my effectivness as a parent. I am glad to report that he recently graduated from college and is fine. And interestingly, most of his teachers thought he was a hoot (I didn't).
And, yes, even he was required mind his manners in public. So, I do understand about difficult children.
