I have a sun/mercury in my 7th house and I have a hard time understanding how it can show up. Since I'm not focused on getting into a relationship and my past experience haven't shown it. I think it shows up in my friendships. I've noticed at different times in my life I usually have one very close friend who my life revolves around. Time spent together, having the same job, sharing transportation/housing. Was wondering if I could get some insight on these placements.
