You don't deserve my kindness.

If you are good to me, I won't be bad to you. If you are not good to me, don't think that I am good to you. This is one thing that everyone knows. That person is mutual. You are good to me, and I will certainly not be bad to you. If you are not good to me, why should I be good to you? So this shows that people are mutual, and no one will be selfless to you for a long time.

So if you are good to me, I won't be bad to you. If you are not nice to me, don't think that I am nice to you. This is the truth of life, which makes sense. Therefore, if others are kind to you in life, you should also repay others' kindness, be grateful, and be a person who knows how to repay kindness.

If you often pay for someone, but that person is indifferent to you, then don't be nice to her again. You don't need to be nice to her anymore, because this person is an ungrateful person. She only takes and doesn't give, so people are mutual. If you are good to me, I will certainly not be bad to you.
