Why won’t the woman go to the party? [br] [originaltext]M: The school’s English

M: The school’s English club is having a party on Saturday night. Can you come?
W: I would like to, but I work at a restaurant on weekends.

W: Now, I should have failed it yesterday, but it doesn’t seem to be here in "paid invoices" and that’s the right file. I don’t understand. . . it’s been paid.
M: Ah, what about this envelope on your chair?
W: Oh here it is! It’s in the right place but it’s attached to the receipt so I couldn’t see it.
