I dunno. "Stop being a ****" is fantastic advice for someone you don't like.
No, it shows that you are friendly or good natured towards everyone. Even if you dislike them
No, but you must try to be careful not to give bad advice just because you don't like the person. Try to be better than that.
We can advise even our enemies if they are in need of our help.
No. You can always choose what you say. It kills me more to do or say nice things for someone I hate, but I'd rather get it over with than live with the guilt after. Most of the time, it works in my favor. Karma.
it wont be wrong for us<br />
but it will be disaster for them
