In "The Outsiders," explain what Ponyboy means when he says Soda "reminds me of a colt."

Ponyboy goes on to say, "A long-legged palomino colt that has to get his nose into everything." A colt is a young horse who is curious about the relatively new world around him, and he's very playful. This is how Sodapop is when they're at the hospital. He's into everything while they are there and even makes a policeman laugh at his antics. It's a new situation for Sodapop that is exciting, and this excitement infects him. But, Sodapop loses interest in the excitement, just like a young, immature person. He's unable to keep his interest in any one thing for very long.
