YSK that silent pauses are normal in a conversation; they don't always mean something is wrong. It's fairly typical for most of us to rush to fill in the silences, but learning how to be comfortable with silence will keep your foot out of your mouth and give you time to think.

YSK認爲沉默的停頓在對話中是正常的；它們並不總是意味着有問題。對我們大多數人來說，急於填補沉默是相當典型的，但學會如何適應沉默將使你的腳離開你的嘴，給你時間思考。
