Believe it or not, Cancers are similar to Scorpios when it comes to how little they trust someone. There is always a suspicion that the Cancerians have that even someone with a close relationship to them may turn on them. They limit their trust to each person, only giving out so much information then withdrawing themselves before they ever get to close. Sometimes, not always, they don’t even trust themselves. In any relationship, secrets are always kept tucked away in the Cancer’s shell. It isn’t to hard to come across a friendship where the friend offers personal stories but the cancer tells none.
