Well that can't have been much fun. 
	She can't be in the canteen 	I've just come back from there. 	He should be in later, 	

if you'd like to call back after lunch. 
	I'm sure you'll pass. 	You've worked really hard. 	He can't have gone home already. 	
His bag's still here. 	It might have got lost in the post. 	You know, these things happen sometimes. 	You must have left it in the restaurant. 	
I saw you take it out while we were having dinner. 	Look. That must be the pilot. 	He's wearing the uniform. 	He can't be the teacher. 	

He doesn't look old enough! 
	Wow! You must love beans. 	I've never seen anyone eat so many. 	It must be hard work bringing up three kids. 	

You can say that again. 
	This must be Julie's. 	It's got her name on it. 	I might go swimming tomorrow. 	
It depends on the weather. 	He might have gone swimming. 	He does sometimes on Fridays. 
	I'd book your ticket now if I were you. 	
It could be really busy. 	I expect we'll go to Tom's party. 	Unless I have to work late. 
	 You might find one in Watsons 
	
I think I've seen one in there before. 	He should be here in a minute. 	He's only got to come from the office and it's just round the corner. 	It should be a great party. 	
They've bought loads of food and drink. 	Don't worry. You're car will be fine. 	I've never crashed one yet. 
	You can't have finished already. 	
You only started five minutes ago. 	She may be off sick. 	She said she wasn't feeling very well yesterday. 	You want to take plenty of sun cream. 	
It'll be absolutely baking when we get up on Tai Mo Shan. 	Don't touch it! 	You never know, it might be a bomb! 	We had to wait in the pouring rain for an hour!
