Chinese proverb

"A bird doesn't sing because it has an answer it sings because it has a song." To me this means you don't need to have an answer all the time but when you do speak it should be from your heart. There are different bird songs. Some are joyful, others melancholy, some yearning and others wistful. You should consider the effect of your words on others. What does this proverb mean to you?
