Those born between June 21 and July 22 are Cancers according to the zodiac. This means that they have a tendency to withhold their feelings from time to time in fear of sharing too much with someone who might not necessarily be trustworthy. If your sister has been seemingly reclusive as of late, this might be the reason.
Cancers also have a tendency to be defensive, but it's important to understand that family is a top priority in their lives. If you keep this in mind, you may be able to let some of your sister's antics slide and take comfort in knowing that she has your best interests at heart.
A psychic who specializes in astrology can help you better understand what makes a Cancer tick if you still have questions pertaining to your sister. During a psychic chat, you can learn more about how the stars influence your everyday life.
