Small and big flaws in each zodiac sign. Cancer: sadness.

Cancer's eyes are always wet. Watching a sad movie with him is like a whirlwind of emotions. Cancers often change mood. One moment they're happy, the next moment they're sulking. That's why Cancer needs true friends who are not offended when representatives of this zodiac sign suddenly become isolated in their shell. As compensation, he is always ready to listen to the problems of others and help in any way he can.
