have some backbone

I told the my friend that I hate one of my superiors.

He said, "Hey, you can't think like that. If you hate people, how would you feel if other people feel the same way about you?"

"Ha? So, I have to like everyone just to make myself liked ah?", I replied.

*I know a few who pretend to be everyone's friend for this sake. It's reasonable too, afterall, why make enemies?*

I continued, "If you don't know what you hate, How would you know what you love?

If you don't know what you despise,

How would you know what you respect?
