Crush at a Buffet

You know when you become a teenager you start to have crushes on cute guys? Well my sister had a crush just yesterday. It was ..... interesting. My dad, Ali, and I are going to The Krazy Buffet for dinner. When we are there my sister starts staring at our waiter. Later my dad gapes at Ali and the start arguing! I ask them what they are saying and my sister said that she has a crush on our waiter! Ali says " He is 15!" My dad says "No he is 18!" This goes on for the rest of the time we are eating! To be honest I think our waiter heard the conversation at least once before we left. I don't think age matters if she was planning on marrying him because she is 13!
