Cancer needs a meaningful family life and tends to extend that feeling of family to the people close to them. Sagittarius can also enjoy the peace of home, but needs to go out, move around and spend time with friends.
The saying “A light in the street and darkness at home” describes the imbalance that can appear if Sagittarius saves all their availability for the outside world. Cancer may feel that home gets only the time left over.
Sagittarius’s tendency to set rules can also feel overwhelming. Humor can ease some disagreements, as long as it isn’t used to leave important needs unspoken.
Another sensitive point is how they react when angry. Sagittarius’s hurtful words and intensity can especially affect Cancer. Taking care with how they treat each other is as necessary as sharing time between social life and family closeness.
