Sometimes we need to get lost from other people we hold on to see for us to know who we are, to develop ourselves, and to make yourself at peace with chaos, and find who you are. Maybe that's the reason why others want us to leave for us to let them fly, let them who they want to be, to prove to themselves that they are better beyond our expectations. I am not wondering others will just forget everything , leave us wherever they want. Whatever the reason they want to convey For me it is your choice and whatever the reason you choose is your own consequences. 

Kids must taught how to accept themselves, their weaknesses as well as their strong points. Some teachers maybe doesn't know how to appreciate their students in which they become haters to other people, they feel envy because they live their lives full in vain, hatred and envy. The first thing I learned is to teach a child to become open minded , to appreciate beauty beyond physical but within themselves.
