Don't be like the people that make you sad
Don't be hurtful like the people hurt you although they don't intend to
Don't judge people like the people judged you
Don't go giving advises although they seemed they needed.
Just listen and support.
Unless they are really in trouble and want the advises.
Do not forget what i am telling you.
Because I don't want you to hurt others like they hurt me.
And remember, take everything as positive!
