Because the Moon rules Cancer and has such a powerful bearing on our instincts, intuition, and emotions, the Cancerian characteristics will be very strong indeed in someone with the Moon in this sign.

The powerful Cancer characteristics will be primarily directed towards the partner and family, and apart from the strong self-defensive system, may well not be at all obvious to those who come into contact with the individual on a day-today or casual basis

Challenge a Cancerian and at once you will see his or her natural self-defensive system come into play. The need to protect themselves and their loved ones is an extremely basic instinct with people of this Sun sign. Used positively it is marvelously helpful, but sometimes it can result in their becoming too easily annoyed, so that a slight "huffiness" is displayed at the mildest opposition.

If you are in love with a Cancer man or woman, give him or her your understanding. This is a sensitive soul who needs to be brought out of the shell with attention and discussion. Patience is important here as often (but not always) this individual is quiet or shy.
