Mercury, planet of communication, rules the sign of Virgo. So you're a pretty smart cookie who knows what you're about. Your mind can hold a ton of stuff, too, from phone numbers to faces, dates and memories.
But you prefer to keep things pretty compartmentalized, with work friends separate from high school friends, and partners separate from friends. Sure, they mix sometimes. But that can cause you stress, wondering if everyone will get along.
On date nights (when you've reached the meeting and hanging out with friends stage), try getting like-minded people together according to their interests, rather than how they're categorized in your mind. You may find that everything works out just fine and even piques a new interest in both of you.
