The English we speak from BBCLearningEnglish.com hello, I'm Fei Fei.
And this is the English We Speak.
And hello, it's Rob here.
Feife, I hope you don't mind me saying, but you look a bit hot and sweaty.
That's because I've been training for this thing that Dan's having for his birthday.
A thing?
What sort of thing?
Well, according to his party invitation, he's having a knees up to celebrate his birthday.
I'm not sure what it is, but I want it to be prepared by getting fit.
Look, I can get my knee up to my chin.
Wow.
Well, that's impressive, but completely unnecessary.
An ease up is an informal way of saying a lively party where there's usually dancing.
So he's having a party.
Oh, right.
So I've been invited to Dan's birthday party.
Well, if there's dancing, I still need to get fit.
That's true.
