On the (way) upside, they're inventive - even quirky - lovers. They hate to be bored, so you won't be either! Aquarians don't just think outside the box, they live there.
If smitten, he or she could probe your politics one minute and take you rock climbing the next.
There's a method to their madness. Pass the "test" and you could be wacky enough to enter their unpredictable world!
