That's not even funny.
On Topic: You're overreacting. How would a first date make a difference? It will be just talking and probably a pizza on the table. Absolutely zero satisfaction, a dinner might actually be perfect, even if you're parents are there, it's usually relieving to know that one's parents accepts you, it doesn't matter if it's your parents or her's. There are alot of relationships that end because of parents that don't like the boy or girl, when one of the partners is underaged. Good luck, mate!
Now that I read your above post:
She's a mood swinger. Stay away from mood swingers. Stay hundreds of miles away, if she likes you she will get with you, but later she will likely step on your feelings like on stepping stones when she is sad.
