Heaven knows we need never be ashamed of our tears, for they are rain upon the blinding dust of earth, overlying our hard hearts. I was better after I had cried, than before--more sorry, more aware of my own ingratitude, more gentle.
...you know that a good, long session of weeping can often make you feel better, even if your circumstances have not changed one bit.
Don't cry over someone who wouldn't cry over you.
Crying is all right in its way while it lasts. But you have to stop sooner or later, and then you still have to decide what to do.
When someone is crying, of course, the noble thing to do is to comfort them. But if someone is trying to hide their tears, it may also be noble to pretend you do not notice them.
Sometimes crying or laughing are the only options left, and laughing feels better right now.
If a kid asks where rain comes from, I think a cute thing to tell him is "God is crying." And if he asks why God is crying, another cute thing to tell him is "Probably because of something you did."
Don't cry because it's over, smile because it happened.
