You must be so tired!

Have a look at this conversation between two friends

Joe: Hi Jim. What’s up?

Jim: Hey Joe. I just finished working a double shift.

Joe: You must be tired.

Jim: Yeah, I am. But I must get this project finished by Friday.

Joe: I guess you must not have anyone in the office who can help you.

Jim: You’re right. When the boss gets back from his business trip, I must talk to him about staffing.

Joe: He must not realize how short staffed your office is.

Must has a few different meanings in English. Do you know how to use must? Have a look at the conversation above once more, then check today’s lesson.
