Clarrise is very observant. She is curious about everything and she asks many questions. Montag thinks she is strange for these reasons because he, like the majority of his society, has been brainwashed. He has been taught not to be inquisitive. He has been taught not to think critically about anything at all. She observes things and thinks constantly. She says she loves to smell things and watch people. She even comments on how other people are not observant:
"I sometimes think drivers don't know what grass is, or flowers, because they never see them slowly," she said. "If you showed a driver a green blur, Oh yes! he'd say, that's grass! A pink blur? That's a rose-garden! White blurs are houses. Brown blurs are cows. My uncle drove slowly on a highway once. He drove forty miles an hour and they jailed him for two days. Isn't that funny, and sad, too?"
Clarisse is full of energy because she is so interested in the world. She is not really "relaxed" because she is always looking for new things to contemplate. She is does not seem to be afraid of Montag or the authorities, so she is not cautious. And since she is always looking for more to learn, she is not satisfied. Montag says she thinks too much. The truth is that he and most of everyone else do not think enough. Near the end of their first conversation, Clarisse shows Montag that there is a man in the moon. She is always observing what is around her: from the flowers to human behavior to the moon.
