You randomly got a golden ticket. Which meant you could get into Wonka's factory. And here you are standing near the gates of his factory, there are 4 more guys standing next to you, who also got golden tickets. A light snowball was falling everywhere , but it wasn't particularly cold. A crowd of people stood behind and made loud noises. And a moment later, the gates open and Wonka comes out to the five of you with a happy and slightly crazy smile "Greetings, friends! I am glad to take you around my factory!"
