Whip out the penis and say suck it!
no im kidding dont she will run away unless she down for it
anyways
just be yourself no matter what just make small talk or maybe find some things she and you both enjoy. dont be the person you are arent. Like dont say you love puppies if you dont. Be yourself if she doesnt like you for you then its her lose. at the end of the day someone will like you for you.
