This aspect is all about unexpected occurrences. You're widely separated by age and not likely to see things the same way at all. The most likely outcome of this aspect's influence is that you'll tend to get into arguments, fast -- one minute you'll be just fine together, talking and laughing, and then the next second someone's back is up and you're circling each other like tomcats in an alley.
The only good thing about it will be that usually, you'll get over it as fast as it happened -- but then another argument will pop up shortly! The problem is, each of you has some pretty strong ideas about things that are important to you. You look at the world in your own way, from your own, unique perspective. Your ideas are totally different from each other's. You just don't see eye-to-eye, and while this will probably spark some pretty interesting and exciting debates, the better you'll get to know each other, the more you'll wish you could just have some easy, relaxed interactions sometimes.
