Outwardly they can appear formidable - thick-skinned, unemotional, uncompromising, obstinately tenacious, purposeful, energetic, shrewd, intuitive and wise, sometimes with a philosophical profundity of thought verging on inspiration. Their intimates, however, may see a very different character, one with a sympathetic and kindly sensitivity to other people, especially those they love. They are able to identify with the situations of others because of the keenness of their imaginations. They are often overly-imaginative and prone to fantasy, sometimes trying to shape their lives to fit some romantic ideal. They are appreciative of art and literature, and especially of drama, where the spectacle and ebb and flow of action and feeling particularly excite them. They may themselves possess considerable literary, artistic or oratorical talent. Their sharp ears and talent for mimicry can sometimes give them success on the stage, though their tendency to be emotional may make them overact. Interestingly - because they give the impression of being down-to-earth - they are often fascinated by the occult and are more open to psychic influence than the average. If they can reconcile the personal conflict of their urge to be outgoing with the reserve that causes them to withdraw into themselves, then at best they can inspire a generation, especially the youthful part of it, by their idealism.
In their personal relationships they are mentally a mixture of toughness and softness, often emotional and romantic to the point of sentimentality in their fantasies; but in real life and in marriage, their loving is not so sentimental but tenaciously loyal. Anyone who becomes a part of her life will never again entirely be free.
Cancerians have a retentive memory, particularly for emotionally laden events which they can recall in detail for years afterwards. They are strongly governed by childhood memories and since they live intensely in the past in memory and in the future in imagination, a chance meeting with someone for whom they had an unrequited love, even if they thought they had conquered the feeling, will easily rouse the emotion all over again.
The Cancerian has many potential faults. They can be untidy, sulky, moody, inclined to self-pity because of an inferiority complex, brood on insults (very often imagined), yet are easily flattered. Cancer is the least predictable of all signs; they are ruled by the moon and have water as their element so their mood swings can be compared to the turbulence of the shifting tides. It is difficult for Cancer to open up and have a close emotionally fulfilled relationship with someone because they are so closed off emotionally and physically to the world. This is driven by their fear of trust, Cancer has a difficult time trusting people. This causes built up anger and resentment inside, the contradictory nature really takes a toll on them and they can have a negative outlook on life, thinking that life is just too hard and miserable. This is unfortunate because when good experiences are to be had, they are skeptical of people and their surroundings and they experience tunnel vision due to their depressed outlook and they miss the nice things and happy experiences in life that make it worth living. In addition to lack of trust for people, Cancer is deeply sensitive and easily hurt, this is the other reason why they have their defense shell in place, to avoid being hurt by others. Cancer lives in the past. They hold past events close to them and often dwell on the past. They have to learn to let go and live in the present instead of spending their time being sick with nostalgia.
However, because the Moon Child has very deep intuitions into the feelings and motives of others, she may detect hostility that is not readily apparent to others, or that is intentionally hidden. You may see or hear her strike out at a seemingly innocent person, but Cancers always know what lies beneath the surface.
The moon symbolizes the soul, the unconscious self of an individual. It is believed to be associated with femininity, fertility, emotions, maternity, family bonds, sensitivity, memory, death and decay. The ruling planet of Cancer tends to move through the entire Zodiac, with such a speed that astrologers believe it to influence other signs too.
