F: I think spring is finally here. ,M: Yep, it sure seems like it. However, it's still very cold at night. ,F: Yes, they turned the heat off 6 days ago.

Ex Input:
M: Hi, Rachel, how are you? ,F: Don't ask. I've had a terrible morning. ,M: Oh no, what happened? ,F: It's my car. I came out of the house this morning and found that the back window had been broken into pieces. ,M: Oh no, that's awful. What were they after? The car's MP3 player? ,F: Yeah, I guess that might have been it. Because they did take that. It would have been OK if that had been all they got. But they got away with my handbag, too. I'd somehow stupidly managed to leave it on the back seat. ,M: Oh, no. Was there much in it? ,F: No, not really, but there was a spare set of keys in there and my home address. Fortunately, I took my new iPhone with me. ,M: Oh, that's terrible. That wasn't a very sensible place to leave your handbag. ,F: I know. I know. I was so worried that they'd come round and rob my flat that I called in a repairman and got my locks changed this morning. It cost me a fortune. ,M: I bet it did. No wonder you came to work late. I bet you won't be making that mistake again, will you?
(A) F: I’m sorry, I don’t understand. Could you say it again? (B) F: I won't leave my new iPhone in car again. Please arrest the thief for me, sir. (C) F: My car was stolen, so I came to office late. Well, anyway, what's our KPI today? (D) F: Thanks for informing me that somebody broke the car's front window, my neighbor.
