With this aspect influencing things between you, don't expect an everyday, calm, ordinary friendship! You could go through a lot of ups and downs together, and you might never come to a place where you feel that you can really trust your bond, unless other aspects have a more stabilizing influence. But at least you'll have a lot of fun together.
There will be a feeling of change between you; you'll never quite be able to pin your friend down or even get a straight statement about what's going on for them. There will be a feeling that if you don't keep changing it up, your buddy will lose interest in being your friend. But after a while, you'll start to wish you could have a more normal friendship. If you like this person enough to want to continue contact, your best strategy will be to suspend any expectations, because they probably won't be met anyway.
