Feifei: Hello and welcome to The English We Speak, I'm Feifei. And, as usual, I'm waiting for Neil, who's late. I think I'm going to get some revenge by playing a few jokes on him - especially as he forgot my birthday yesterday.
Neil: Hi there, sorry, I'm late. Welcome to The English We Speak, I'm Neil and with me today is Feifei.
Feifei: I've done all of that.
Neil: OK, how are you, Feifei?
Feifei: Not... good...
Neil: Oh dear. What's the matter?
Feifei: I can't believe you forgot.
Neil: Forgot? Oh no, what have I forgotten?
Feifei: What haven't you forgotten? Well, for a start, you were supposed to meet me an hour ago.
Neil: Really? I thought I was only five minutes late.
Feifei: An hour and five minutes late. Secondly, you were supposed to be dressed smartly as we are meeting that very famous guest later.
Neil: Famous guest?
Feifei: Yes, our very famous guest.
Neil: Who's that, then?
Feifei: How could you forget that Justin Bieber is coming in?!
Neil: What!? My hero, Justin Bieber?! Where?! When?! Hang on a minute, Justin Bieber isn't coming in. I wasn't born yesterday, Feifei.
Feifei: You weren't born yesterday but I was - well, twenty-something years ago. It was my birthday! And you forgot! In English, if you want to tell someone that they haven't made you believe an obvious lie, you can say I wasn't born yesterday. Here are some examples:
A: Did you know that I was the third man on the moon? B: I wasn't born yesterday. You're British and I know that no British people have walked on the moon.
A: (Radio advert) Learn Russian in 3 days with just one minute's study an hour! B: Those adverts are so stupid! The only way to learn a language is years of hard study and practice. I wasn't born yesterday. Feifei: So, you can say \"I wasn't born yesterday\" to show that you are not easily fooled.
Neil: And I wasn't born yesterday, so I know that Feifei's claim it was her birthday yesterday isn't true.
Feifei: No, that bit is true.
Neil: Yeah, right. As I say: I wasn't born yesterday.
Feifei: I was! I really was born yesterday. I had a party and everything. Where's my card and present?
Neil: You're not going to fool me.
Feifei: Argh, you're so annoying! I never forget your birthday, Neil.
