Mr 5: Teacher, what does professional mean?
Teacher: That’s a big word. It means somebody is good at what they are doing. For example, if a person is very good at playing football, he can become a professional footballer. In short, we call him a pro footballer.
Mr 5: I am a pro milk drinker and my mother is a pro artist. Crystal is a pro writer because she has beautiful handwriting and you are a pro smacker.
Teacher: Why am I a pro smacker?
Mr 5: You are very good at smacking us!
