Befriend a quirky brunette who happens to be caught in a melodramatic love triangle with two hot guys and only speaks in one-liner witticisms.
Play a musical instrument and practice 24/7: piano, violin, drums (if you play drums, you better keep it a secret from everyone other than said brunette friend; that, or bring shame to your family).
In the rare instance where you don’t play any instruments, be OBSESSED with indie bands nobody’s ever heard of. I’m talking stalker, fan girl obsessed.
In fact, just be obsessed. With everything. Like Hello Kitty. Or hats with ears.
Play a high school teenager when you’re actually 27 in real life.
Wear nonsensical combinations of clothing to show how non-conforming and creative you are.
Always sport HUGE nerd glasses. The bigger and horn-rimmy-er the better.
Be super valedictorian smart and have super strict parents. Obviously.
Wonder why all the “good” female roles are taken, or located in Canada, and just settle for perpetuating the Hollywood archetype.
