This aspect might not be the easiest one to deal with, but it could strengthen your friendship. Just be aware that under the influence of this aspect, your friendship will be tested. Hard times could arise in your lives, forcing you to depend on each other in big ways -- much more than you might have anticipated.
External circumstances will both test your bond and strengthen it. You'll end up surprising yourselves with how well you'll unite as a team and work together to come through the adversity in one piece. But this aspect could also take a different form; it could be that difficulties will come up within the friendship itself, and you'll each have to work hard on your own to meet the challenge. As a team, you've got lots of strength and grit.
