Doug: Do you want to eat my tomato? I don't like them. The only topping I like is ketchup.

Liz: Sure, I love tomatoes. They're a healthy food.

Doug: That's true. Are you sure you don't want anything?

Liz: Well I know the French fries are very unhealthy, but they look so good.

Doug: Come on Liz, try one. It won't kill you.

Liz: Well alright, I'll have just one.

Doug: Great! I'm going to get a refill of soda.
