The second name could be Smith. That looks like an 's'.	She can't have gone home.	Her coat is still here.	That must be his girlfriend.	
Look, they're holding hands.	Who's that at the door?	It must be the postman – he always comes around this time.	I can't find my keys anywhere.	
You might have left them in the car.	I wonder who sent me these beautiful flowers.	It must have been Mike – he's so romantic.	I can't understand how the burglars got in.	
They must have climbed through that open window.	Anyone know where Julie is?	She may have gone home. She sometimes leaves early on Fridays.	What on earth is that?
It can't be a plane.	
It's flying too low.	He didn't eat much rice – look he's left half of it.	He can't have been hungry, then.	Have you seen this phone bill? $10,000!	
It must be a mistake – we only make local calls.	Where's Tony? I've looked everywhere for him.	He can't be far – he was here a minute ago.	Whose umbrella is that?	
It must be Laura's. She was here earlier.	They haven't sent the blue paint we ordered.	They might be out of stock, I suppose.	I wonder what's happened to Richard. He's half an hour late.	
He could have got lost – he's never been here before.	My tummy feels really strange.	You must have eaten something. 	Who's that guy sitting next to Andrew.	
It must be his dad. He looks just like him.	You can't have finished already.	You only started five minutes ago.	She must have passed.	
She's worked really hard on the course.	I wonder who snitched on you for being late.	It must have been that little toad Nigel. He hates me.	What do you think it is?	
It can't be a book – not heavy enough. It could be a CD, I suppose.	I wonder why they left so early.	They must have been tired – it was after midnight.	This computer is so slow!	
You must have got a virus. You're always downloading software!	That’s the doorbell. Do you think they're here already?	They can't be. It takes at least an hour to get here from their place.	I can't read this signature – can you make anything of it?
