Molly	Who wants to go to the victory parade tomorrow with me?
Susan	I will! I have been following this team all season! The games have been the best. And maybe their quarterback is the best the school has ever had! It will be a great opportunity to network and promote our new brand of beer, Winner's Ale!
Jeff	That might be fun. But I worry about our competitor and their contracts with the University and the stadium sponsorship.
Molly	Ahhhhhhh.True, I didn't think of that... Well, we could do it off the record... Hahaha.
Susan	Yeah right, if corporate finds out, we will be fired for sure... Or worse.
Jeff	True true, but I still want to see the game and at least analyze our competitor's marketing strategy.
Susan	Good point Jeff; we will go but you better keep your mouth shut.
Jeff	Thanks Susan, I will, so we'll all go and take notes right?
