You'll find your friend frustrating to be around for any length of time unless there are plenty of other harmonizing aspects between you to tone down the challenging energy of this one. There will always be at least an undercurrent of competition, defensiveness and combativeness between you. Something about your friend's personality will rub you the wrong way, and elicit passionate reactions from you that may surprise even you.
You'll rub them the wrong way, too; your drives and ambitions will seem off-target to them, and you can bet you'll have more than a few disagreements. Still, you'll feel drawn to each other, and the relationship could run high and low like a roller coaster. The frustration of these ups and downs could mount over time and spell the end of the friendship, but it doesn't have to be that way. This connection could, in fact, be a positive learning experience for both of you, teaching you to be far more patient, compromising and compassionate than you've been in the past.
