Do

Neil: Hello and welcome to The English We Speak. I'm Neil Edgeller.
Feifei: And I'm Feng Feifei. Neil, you look terrible! You've got red eyes, grey skin and your voice is so rough!
Neil: Oh, Feifei, you're right. I feel terrible. I went to a leaving do last night and I drank too much beer ... and wine ... 
Feifei: A leaving do? Do?
Neil: Yes, a leaving do. A colleague has got a job at another company and had a party to celebrate his last day.
Feifei: So it was a party?
Neil: Yes, that's what I said. It was a leaving do.
Feifei: Right, so 'do' is a noun and it means party?
Neil: Yes, that's right. It's British English. Urgh.
Feifei: Ah, so in British English, another word for party is 'do'.
A: Did you enjoy Mary's wedding?
B: Oh, it was an amazing do. The food was delicious and there was an excellent band playing. We danced all night!
A: Oh, hi Dave. We're having a bit of a do on Saturday and wondered if you and Sally would like to come over?
B: Thanks, that would be great. You two always put on a good do.
Feifei: So is this a common word?
Neil: Yes, you'll hear it all the time: especially in certain phrases.
Feifei: Like what?
Neil: Well, a leaving do.
Feifei: A leaving do.
Neil: And a bit of a do—we're having a bit of a do.
Feifei: A bit of a do. So, was it a good leaving do last night?
Neil: Um, yes, yes, yes it was very good ... I think. I can't really remember ... 
Feifei: Go home and get some sleep!
Neil: That's a very, very good idea. Bye for now.
Feifei: Bye!
