You like Earth. It's your home and as long as it isn't destroyed, you plan on staying here. All things Earth-based are good and everything from the rest of the galaxy is bad. You have an unlimited capacity to be shocked and astonished, not to mention an incredible ability to drink tea. You aren't as dumb as people think you are but you aren't half as smart as you'd like to be. Common sense is your strong point, unfortunately, the universe doesn't make sense of any kind, never mind common.
Some words of advice: Don't Panic!
