Haven't slept a wink

Neil:	(Yawning) Welcome to The English We Speak with me—a very tired Neil—and Feifei.
Feifei:	(Yawning) Hi, I'm Feifei.
Neil:	Oh, Feifei, I'm so tired.
Feifei:	Me too. The kids?
Neil:	Ah, the kids kept me awake all night. As soon as one of them went back to sleep, the other one started screaming. What's your excuse?
Feifei:	A mosquito.
Neil:	A mosquito?
Feifei:	Yes, there was a mosquito in my room. Every time I turned the light off and tried to go to sleep I heard buzzing in my ear. I haven't slept a wink.
Neil:	And I haven't slept a wink either! A wink is when you close and open one of your eyes very quickly once—usually to show friendliness or that you are having a joke with someone. It's also a verb—to wink.
Feifei:	So, if you say 'I haven't slept a wink' it means that you've had so little sleep, your eye didn't even close once!
Neil:	That's right. It's an exaggeration. Here are some examples:

A: You look terrible! What's the matter?
B: I haven't slept a wink. It was a really bad idea to move to a flat next to a pub.

A: How about a trip to the cinema tonight?
B: Sorry I can't. I haven't slept a wink. There were cats outside fighting all night.

Neil:	So, we can use 'I haven't slept a wink' to say that we are very tired because we haven't had much sleep. (Yawns) I can't wait to get home tonight and just jump into bed ... I don't know how I'm going to get through the rest of this programme, let alone the rest of the day.
Feifei:	Me neither.
Neil:	Nice and quiet in here, though, isn't it?
Feifei:	And dark.
Neil:	Do you think anyone would notice if we just ...
Feifei:	That's a great idea! I'll just put these two chairs together.
Neil:	And I'll rest my head on this desk and ... (snoring). (Sound of babies screaming and mosquitos buzzing)
Both:	Argh! Kids! Mosquitos! Is there anywhere to sleep? Argh!
