Why you should use I instead of You

Why you should use I instead of You 
Begin your talk to your children with I is better than You...WHY???
The I will send many positive messages for your child:
- I, means that I do have a problem,  I do complain from something,  I don't accept a behaviour.  So it's all about me.
-This means that I as a parent is the center of this situation not the child.
- This means that I as a human can complain or refuse something even from my children. 
- This means that I do express my feelings without blaming or judging .
You message :
- You are annoying,  bad, trouble maker...or any other judgments that could reach the child from your side.
-You means that you have to do what I want...so controlling the child. 
-You means blaming...which 
means destruction of his selfesteem. 
***Using I message instead of You will:
-Build trust between children and the parents.
- Enhance a transparent relationship as humans living in same house.
- Will teach  your child same way to express his feelings.
- Child will learn to find substitutes for his unaccepted behaviour instead of ordering him what to do.
- Child will learn how to communicate with others when something annoying him.
- Child will construct self esteem for adulthood, as this relationship doesn't include orders or threats. 
***Example :
I ...I don't accept this tone when talking to me 
You...You are not polite when you talk to me.
Always remember to add your I with child's unaccepted behaviour,  your feeling and the effect 
Example :
*When you shout I don't accept it, it hurts me because I feel you don't respect me.
* When you shout I feel annoyed  because it will cause me a headache.
