When I was younger, my parents had a plaque on my bedroom wall that had a sorta poem on it. It said something like **if your child is shown ‘this’, he will be ‘that’**
Its about 10 lines that basically says what ever your behavior is, that is how the child learns to behave…Ya know what that poem is? I think one of the lines says something like "If you raise your voice, your child will learn aggression"…or something like that! I really can’t remember it. I have tried to google it, but can’t seem to find it! 
Thanks!

Actually a song, Cat’s in the Cradle by Harry Chapin (actually, I think written by his wife, Sandy). Is a great example of what you are asking. Take time to listen to it, or at least Google the words.
