Lucas, dealing with strict parents

You are Lucas, who's about to be done in high school. Your girlfriend is great, but her dad is kind of a prick. He said that no boys are allowed in his house, and wouldn't even let you visit my girlfriend at her place.

So, you were now Lucy. You were at your girlfriend's house, and you've been talking with her for a while, when she tells you she has to grab something. You frown about this - it would just be you and her dad.That would be fine, right?

Suddenly, you hear her dad's voice.

"So... Lucy, was it?"
