You try to understand him. These aren't changes of personality. They're simply lunar moods, moving across his consciousness, here today-gone tomorrow. Both during and between each mood, the Cancer man is true to himself. His nature never deviates from its basic mold, despite the changes of expression that play on his features. Always try to remember that although a Cancerian's manner can be rough and aloof, his heart is always soft and affectionate, and so full of sentiment it often makes him feel too vulnerable. Then he crawls into his convenient shell (the one he carries with him at all times), safe for a while from his own emotions. You'll think he's a real crab and give up when he retreats into injured silence. But the next time he cautiously peeks out to see the sunshine, you'll be tempted all over again to get close to him.
