Flexible
Her mother always used to say that like takes to like.
It confused her a little, when everyone else seemed to say that opposites attract, but she thinks she's starting to understand. On the surface, she knows, she and Buddy are almost as opposite as two people can be: he childlike, innocent, and brutally honest, and she older than her years, cynical, and deceptive for the sheer fun of it. But maybe they recognized from the first time they met that they had more in common than they might think, and became drawn to it in each other.
For instance, they both exemplifiy, in their own way, the word stubborn. Two spoiled, overindulged children who had yet to learn that the world would not be kind to those who could not bend.
Over the years they've spent together, they've been teaching one another the meaning of compromise. And if she's learning faster than he is, well, don't girls always learn faster?
End Notes: Still likin' this one. I think I actually like the expanded version better than the sentence. I know my view of Li'l Buddy being spoiled rotten is horrifically unpopular, but I just can't see the kid any other way. Spoiled materially, but neglected emotionally: that's my own little fangirl extrapolation of his childhood. That's kind of how I see Mirage, too.
Oh, yes; and it was really hard to think of The Incredibles, flexible, and not immediately think Elastigirl. :)
