If you don't like her laugh, you're probably not gonna watch her after checking her out or giving her a chance. But if you do, you're gonna end up stuck with her in your life. She laughs a lot and it's pretty genuine, not a fake one. It's great because it means she's having a good time and since it's an infectious signature laugh, it helps set an atmosphere where everyone can laugh with her.
It's like one of those cliché sayings: people who laugh the loudest hide the darkest sorrows.
