Approach the girls

They giggled at you. There must be a reason. You go up to them and think about what to ask, but they start before you have a chance to say something.

"Hi, you're the new guy?" the right one says. She has black, slightly curly hair.

"Uh, yes. How did you know that?" you ask.

"Our teacher, Mrs. Hangton told us you'd be coming this week," the left girl explains. "I'm Kimie, by the way." She has straight, red hair and a couple freckles on her cheeks. She is very slim, compared to her black-haired friend who is a bit curvier.

"I'm Caroline," the black-haired girl says.

"Nice to meet you both."

The bell rings.

"Uh, class starts. Wanna come with us?" Kimie asks you.

You feel a slight urge to go to the toilet. You can't really tell them to wait for you while you're using the men's room, now can you? Do you want to follow them or decline and hurry to the toilet while they can go?
