Kangaroos surprise you.

There are moments. Moments when you are with a kangaroo in a new and strange land, and it's right in front of you, so close that it's touching you, so you reach down and pet it. Moments when that small, three foot tall kangaroo looks up at you, with this look in its gentle black eyes: a combination of curiosity and contentedness. There are moments when you look at that kangaroo, eyes locked in mutual understanding, and you just know that that kangaroo is taking a dump on your shoe.

But then he hops away, and you see that he didn't take a dump on your shoe. And then you realize -- that's what kangaroos do. Kangaroos surprise you.
