...a "hard head" makes a "soft behind"...
You can't deny it... you had to get your head "bump'd" too! and furthermore, you know yourself, that everything your parents told you "not" to do ... what happened? ... You did it anyway, and don't say you didn't. So now, don't be "trippin" wit' cha kids like you've been "Mother Teresa" all your life, cause you and I both know - we all been "hardheaded" at some point.
Lighten up, a little! I realize a lot of today's "heathens" don't have any respect, but not all kids are that bad. Listen, sometimes the reasoning behind their actions may have a lot to do with those personalities that are still developing, and you don't want to "cripple" the mental and emotional growth of a potential politician, doctor, film producer, or "repo man" (? - hey, who knows what people aspire to be...) do you? You'd be surprised to know what these kids are thinking. You didn't "get it" until when? ..., ? ..., ? ..., my point exactly. If "we" had gotten it sooner, we would have saved ourselves a "whole lot" of heartache throughout our lifetimes.
True enough it may seem your son or daughter has an "attitude", but could that be partly due to that habit you have of embarrassing them in public? You can't just say any and everything to a person, especially in front of strangers. Don't call your son "that Ni_ _ a" in public, (or behind closed dooors either), and while I know you might "rupture an Artery in your neck" doing so, please refrain from threatening to "slap the S%#@!" out of your daughter, because - guess what? something may really happen that you'll get blamed for ... or the next time your child has an issue or crisis, they will be reluctant to call on you because not only are they ashamed of you, but they probably "can't stand your Crazy butt!"
I know things today are "outta control", and your kids are not the first to come home and say ... "my teacher doesn't like me." I used to respond this way to mine... "those people did not go to College all those years to obtain degrees, and go into the classroom, to teach kids they don't like" ... I take that back. Some of these children are "not" lyin', the teachers don't like them. They don't like their jobs, they don't like each other, they don't like anybody. Granted, some kids are indeed "fabricators", but you should know your child. You should know what you live with, and what you are "raising." ... Especially because you "used to be" a child, and you know the type of "mess" you tried to get away with. Yes. You - don't be tryin' to act "brand new", cause none of us are squeaky clean, and if you "think" you are, you "perpetrate'n" and you know it. O.K. that's all. Just had to get that off my chest, cause I don't like seein' kids stressed out by their parents, (or any other adult for that matter) - they've got the rest of their lives for stress - and they'll still have you! ... Holla!!!
