Here are some suggestions to complete the dialogue:
- Hi, my name is ____. I couldn't help overhearing you talking about your plans with friends after school. It sounds really fun!
- Sure, I'm Alice. My friends and I usually hang out at the mall or go to the movies on Fridays. What kinds of things do you like to do?
- I like doing those things too. I just moved here and don't know many people yet. It would be great to meet some new friends.
- Great, I'm always looking to meet new people. Why don't you join us this afternoon? We're meeting at the mall food court.
