These signs are similar but also very different. Gemini is always using his quick mind to analyze people the second he meets them, and Cancer is always feeling people out based on their emotions. They like the mystery of people they don’t know, and they will enjoy getting to know one another as well. They will come close to understanding each other, but never completely. Gemini will always have a hard time understanding what she is feeling, and Cancer will have a hard time understanding what he is thinking.
