chat_history: ['I never liked milk growing up, because my family drank skim.', 'Do you like it now?', 'Well, first I tried whole milk, and that was gross. But I just tried 2% milk, and I like it!', "I like 2% as well.  It's perfect for cereal and chocolate milk!", "I agree! I'm so happy I can enjoy it now."]
sys_response: Have you tried 1%?
situation: I never liked milk. I always had skim milk growing up. Then I decided that maybe whole milk would be better, but I didn't like that either. But now that I've had 2% milk, I can enjoy it.
