In friendship and in life, you hold fast to your loyalties with a strength in your
convictions. You keep secrets as well as promises, whether they pertain to
others or yourself. Although you are often hesitant when it comes to trusting
value on the advice of those you know best and are easily influenced by
their desires. You have a love for all things spiritual and magical but
believe your greatest treasure of all to be the home. You value
harmony and happiness and do your best to make those
around you comfortable at all times. Cancer-born people
often become successful leaders in the worlds of the realm
although they are most content in the homes.
