People with Mercury in Cancer are somewhat emotional in their approach. They form opinions and ideas about things and people quite fast but are usually reluctant initially in making a relationship with someone. They try to get the real emotions hidden behind the words and they will tell you what you have told them earlier many days or months back. They may have a solid and comforting voice. They will try to make one feel good while talking to them. They tend to do one thing at a time and that too very systematically. They can bring up arguments but do not like when others start arguing with them. They like to speak on topics which are on hand.
