I loved you enough to ask where you were going, with whom, and what time you would be home.
I loved you enough to insist that you save your money and buy a bike for yourself, even though we could afford to buy one.
I loved you enough to be silent and let you discover that your new best friend was a creep.

I loved you enough to make you take that Milky Way back to the drugstore
 (with a bite out of it) and tell the clerk:  I stole this yesterday and want to pay for it.

I loved you enough to stand over you for two hours while you cleaned your room --
a job that would have taken 15 minutes.

I loved you enough to let you see anger, disappointment and tears in my eyes.
Children must learn that their parents aren't perfect.

I loved you enough to let you assume responsibility for your actions even when the penalties were so harsh they almost broke my heart.

But most of all, I loved you enough to say NO even when I knew you would hate me for it. 
Those were the most difficult battles of all.
I'm glad I won them, because in the end you won, too.

It is easy to give in to teens when whey rant about chores or things they may want to do without parental authorization. Raising good kids requires that clear expectations be stated often -- much before altercations arise. Repetition is key to ensuring that a child understands your position on a given issue or behavior. When in impasse arises in relation to choice of friends, use of drugs, and the kinds of activities in which the child wishes to engage,  it is important for the parent to stick to his guns. As the child grows and an understanding is reached about why given rules have been put into place, it will likely be necessary to modify issues such home arrival times and activities that can be engaged.  A child grows up only once. Allowing he child to "chill" with friends who appear to engage in negative activities and behavior, can result in a child's life-long involvement in gang/activity or propensity for abusable substances. The longer child engages in a gang or in drug use the more difficult it becomes to ask the child to extricate himself from these, and the more difficult it is for interventions to work. 

Talk to each of your children. Get to know each one of them. Create an openness such that they can talk to you about anything that might be on their mind. Discipline with respect for the individual, avoiding ridiculing him or putting him down. The result of discipline should be compliance as a result of  the child recognizing that he is being helped.   Rob Gallardo
