Ben: Hi, Ian. How are you?
Ian: Hello, Ben. I’m OK, but I have a lot of work to do and I am trying to finish it.
Ben: Really? And I’ve called because I want to invite you to my son’s party. We are celebrating his graduation.
Ian: A party? It sounds fun, but I am staying at work till late tonight.
Ben: Again? You always leave the office late!
Ian: That’s not true! But, anyway, what time does the party start?
