 {'role': 'USR', 'utterance': 'Did you fix your guitar? My sister has a new guitar you can probably borrow if your guitar is still broken.'}
 {'role': 'SYS', 'utterance': "Thanks, but I can only play music on my guitar because it's a left-handed guitar...it's for people who use their left hands for most things. I fixed my guitar on Monday night."}
 {'role': 'USR', 'utterance': "Why didn't you fix it sooner? We only have two days until our show."}]
