Y:Oh, look, it is almost 6:40!
F: What's wrong with John. He used to be punctual.
Y: Yeah. Hope everything is OK
F: Maybe because of the traffic jam.
Y: It's the right time people finish their work and go back home
F: Yes. So many people drive cars now. There are always lots of traffic jams in this city.
Y: I am still a little worried about him.
F: Yesterday John said that he would have a meeting today. Maybe it came to some troubles to solve.
Y: That makes sense.
F: Do you have his phone number?
Y: No, but I can ask Lynn. I remember that she has John's number.
F: We'd better make a call.
Y: OK.
