What are the sentences that express kindness to others but don't get the true meaning?

1, I think that if you treat others sincerely, you can also get others to treat them sincerely. I tried my best not to let the people around me feel sad, only to find that I was injured. After some things, I realized that I was really stupid.

2. Life has told me again and again that sincerity can't be exchanged for sincerity.

It seems that every time I really can't get equal love, it seems that many people leave for the first time.

4. Because I am eager for friendship, I am eager for other people's care and concern. I do what I don't like, say what I don't like, and deliberately pay and please, but I can't get the sincerity you want. I want to be simple and sincere, but I don't want to lose my heart.

A casual remark is often laughed at. My silence now will be indifferent in the future. Sometimes you really can't change your heart, so be indifferent!
