If you choose to be a person who sees things positively, even if someone were to do something to you with negative intent, you can only gain positive results from it.
This does not mean you should simply tolerate someone who acts toward you with negative intent.
Nor am I saying you should forgive that person's negative actions.
Rather, it means that even in such moments, by interacting with that person through unconditional love, you yourself can gain positive, favorable outcomes from the situation.
