M:Excuse me. May I have some information about the reception party that you are advertising outside? It’s for new students, isn’t that right?
W:That’s right and what would you like to know about it?
M:Well, I’m not really sure what the purpose of the event is.
W:The party will provide students with a chance to get to know each other, and a chance for students who have successfully been through university to pass on some valuable advice.
M:Who’s organizing the event? Is it the faculty or...?
W:Actually, it is the Alumni Association. So, It’s strictly a student-to-student event.
M:I hope we won’t have to sit through a lot of boring speeches. I mean, aren’t these students just "brains" anyway? What can they actually do to help a guy like me?
W:No, these people are not"brains" at all. The Alumni are simply a group of normal, but grateful students who hope that, by sharing their experiences with new students, they can help more students to successfully graduate.
M:But will we have any time for some fun at this party?
W:Most of the time will be split between eating, dancing, and singing—so not to worry. However, some words of wisdom from the former students should not be missed.
M:You’ve got a point. Those are, after all, success stories if they’ve managed to survive university life. I hear about only half of all students who start university actually finish it.
W:And besides that, there’s another reason to go.
M:What’s that?
W:The pie they’ll be serving is delicious. I know it since I’m the one who will be making it.
