Modals of Probability

Listen to a conversation about the boss as two workers use modals of probability to guess why he is in a bad mood.

Ray: Hey, did you see the boss looked in a really bad mood as he came in today. I wonder what that’s all about?

June: Strange, he looked happy yesterday.

Ray: Well, it may just be he had a row with his wife this morning.

June: It might. But he may have had an accident on the way in.

Ray: Yeah or he could have found out about you Skyping instead of working. Haha.

June: I hope not. Now look, Rita is going into his office and she doesn’t look happy. It must be something to do with her.

Ray: Yeah you’re probably right. Hmm, I wonder what that is. Well, we better get back to work anyway before he sees us gossiping.

June: Yeah. See you later.
