The mascot of Cancerians is the Crab, and much like this shelled little critter, Cancerians are quick to retreat into their shells if hurt or uncomfortable in a situation. For Cancer, it's not that big of a deal, though, since they consider this 'shell' a second home (and they do love home). The shell-bound Crabs are very comfortable in their own space. What to do? Give the Crab time -- eventually these folks will come out to play again. It's said that Crabs are first to laugh and first to cry, so you can bet they'll fill you in. That shell, by the way, isn't the only tough thing about Crabs. These folks are tenacious and strong-willed and work hard to get what they want. Their well-documented kindness and gentleness mixed with their strong will and hard work does the trick almost every time. That said, any self-respecting Crab would tell you that they are ultimately motivated by protecting their home and loved ones, a most noble goal.
