Your mother has just died. Someone you love has cancer. Your spouse has left you. You are struggling at work. More likely, you have simply broken down. You burst into tears. So you pick up your tear cup, put it under your eye, and weep into it. When you are finished weeping, you cap it and put it away again. It is a way to save your tears.
Why save them? Because they are precious. It doesn't matter why you cried, your tears are still precious, for they show that you care. A full cup of tears is proof that you have felt deeply, suffered, and survived.— Forrest Church in Life Lines
