W: Hi, ...Pete?
M: Nice to meet you, Mrs. Green.
W: It’s nice to meet you, too. So, are you enjoying the party so far and what do you think of the food here? I see you talking with so many people here.
M: Yeah, it’s great. This might be the last time I see some of these people for a long time, so I’ve been pretty busy chatting with them. I haven’t had much time to sample the food but I believe the food must be delicious and I can’t wait to enjoy the food.
W: I know what you mean. I can’t believe that all you kids are finally graduating. Donna has grown up so fast because she looked like a little girl only two years ago and I haven’t thought that she could be a graduate student now! Do you have any plans after graduation?
M: Well, I’ve applied for a teaching job overseas because I always dream of working in a totally different environment experiencing a whole new culture and meeting new people and making new friends. I guess I’ll probably find out if I get the job or not next week.
W: You’re more adventurous than Donna. She’s going to take a job right here in town, at least for the summer. After that, who knows?
M: Well, you might be seeing me around here for a while longer, too. Oh...wait a minute. I’m sorry. I think Dan is leaving the party because he has to catch a flight to New York where he will start his new life by working as a programmer in a big IT corporation. Excuse me, Mrs. Green, I’ve got to talk to him before he goes.
W: Certainly. It was nice meeting you, Pete.
M: Same here.
W: Oh, and good luck with your job search.
M: Thanks. Thanks a lot.
