[update] Proverbs, by Shey

Beauty is not in the face; beauty is a light in the heart.

Sometimes we believe in the reliable people that have good appearance or like polite, but in some situations these people show us how they are truly and this let us down.
Dialogue
Bob: I’m so disappointed with coworker.
Peter: What happened?
Bob: She like a good person, she always polite so I thought she was a reliable person and I told her about a project that I wanted to show to my boss because I’m working hard to get a promotion. So she said me it needed some repairs and asked me did this, how I thought she was reliable person I agree with her and gave my project to her. So she shows my project to our boss how it was her and she got my promotion.
Peter: That’s awful but the proverb says beauty is not in the face; beauty is a light in the heart.
