Mercury in the 3rd House (Composite)

In the composite chart, Mercury falls in the 3rd house, so the way the relationship thinks, talks, and exchanges ideas is focused on talking, learning, errands, and the everyday mental life that runs between you. The composite chart portrays the relationship as its own entity, and Mercury shows the mental life that runs between you: how you communicate, make plans, and understand each other. Here, the bond does its talking and thinking through this area of shared life, for better when it flows and for worse when wires cross. The gift is a natural channel for understanding in communication and daily exchange; the work is meeting it consciously, since this is where the relationship most lives out its communication and shared thinking.
