i was reading a book when the author described "sammie's" (one of the character) mum as an "emotional cancer." somehow it got me wondering i mean my horoscope is also cancer. so i decided to google "cancer horoscope and personality." and this is what i found interesting.

Crabs live in the inter-tidal zone of the oceans, where tides rise and fall twice every day. This is the most dynamic and changeful place on earth, but also the most nutrient rich. Because of the constant change, Cancer have developed a hard outer shell for protection. Cancer can use the hard outer shell of your home as your protection. But it's more than just that. Typically, your sensitive Cancer can hold your feelings quietly behind your own walls.
Crabs also have large pinching claws, and Cancer can hold onto things, especially from the past. Cancer are fiercely loyal and have a difficult time letting go. But Cancer are also quick to bring those you love inside the safety of your outer shell while you nurture them. Cancer love is protective, but unless tempered, can be smothering.
Cancer motto could be, "A good defense is the best offense." Like a Crab in its cave, your attack can consist of baiting your opponent into your territory. What appears to be a retreat to others can be your best aggressive tactic. As you feel your way through life, building your security by developing your home and family relationships, remember that unexpressed anger can turn into resentment and depression, so find someone you can trust and share your feelings.
