沉默太沉重

'Silence is too heavy.' Silence may contain rich emotions. People often think that only when one speaks too much and then falls into silence does the weightlessness appear. But there is a type of person who stays silent at the first contact. They bear a great weight because they know the past cannot be erased, thus they tend not to open their mouths easily. So for them, the moment of silence is like bearing thousands of words, hence they choose this name.
