Zhenis: Hey! Who's eaten my ham sandwich? I was looking forward to that.

Will: It' must have been the dog, I'm sure. He always eats food that's
lying about.

Will: What about Steve? He ......... (take) it by a mistake. He ..........(think) you made it for him.

Zhenis: No way! Steve ......... (eat) it. He's a vegetarian.

Will: Right, so it ......... (be) someone else. What about Kanat?

Zhenis: I suppose it ........... (be) him but it's not the sort of thing he usually does. No, I don't think it was him.

Will: And it ......... (be) Dave, because he's visiting his parents this weekend.

Zhenis: You're right. So it's not Dave, it's not Kanat, it's not Steve and it's not the dog. That leaves one person: You. You ....... (steal) it.

Will: Oh, that ham sandwich. Was it yours? I'm sorry.
