The next time you're a little bored, and none of your friends are free to hang out, go chill at the observatory for an hour and learn about constellations. Then, when you drop some knowledge the next time you're talking about stars, everyone will be impressed at your smarts. Also, you'll have things to say during those long nights spent outside with your girl.
