i love you, but I don't agree with what you do

I promised myself, that I'd never be like my mum when i grow up.
As in her temper and the way she disciplines, never with patience and understanding, never stopping to understand the situation fully before giving out the punishment, always resorting to nagging.
NO.
I won't do that to my child.
I promise myself.

I'm sorry. I love you, but i don't agree with what you do.
