 People believed for a long time that heart was the center of a person’s emotions. That is why the word “heart” is used in so many expressions about emotional situations.

One such expression is to “lose your heart” to someone. When that happens, you have fallen in love. But if the person who “won your heart” does not love you, then you are sure to have a “broken heart”. In your pain and sadness, you may decide that the person you love is “hard-hearted”, and in fact, has a “heart of stone”.

You may decide to “pour out your heart” to a friend. Telling someone about your personal problems can often make you feel better.

If your friend does not seem to understand how painful your broken heart is, you may ask her to “have a heart”. You are asking your friend to show some sympathy(同情) for your situation. Your friend “has her heart in the right place” if she says she is sorry, and shows great concern(关心).

If your friend says no to you, do not “lose heart”. Be “strong-hearted”. Sit down with him or her and have a “heart to heart” talk. Be open and honest about your situation. Then you may have a “change of heart” Then you could stop worrying and “put your heart at rest”.
