Akiko: You need a heater. (Suggesting)
Lisa: I need a heater. (Agreeing) The question is what kind? (Defining) You use kerosene, don't you? (Checking)
Akiko: Kerosene, yes. (Confirming) It's the cheapest. (Comparing)
Lisa: But I like clean air. (Protesting) Don't you get a kerosene smell with yours? (Probing)
Akiko: A little. (Admitting) It does smell a bit. (Admitting) It didn't when it was new. (Defending) Really, if you want clean air though, electricity's the best. (Opining) A combined AC and heater? (Suggesting)
Lisa: But so expensive! (Protesting)
Akiko: Hmm. How about a gas heater? (Suggesting) It's cleaner burning and if you're careful, it doesn't cost so much. (Compromising)
