A: It's time to start work.
B: Okay, where do we start?
A: The best place to start is the roof.
B: The roof? Isn't that dangerous?
A: Don't be afraid. As long as we're careful, we'll be alright.
B: But I'm afraid of heights.
A: I'll be there. Like I said, we'll be okay.
B: Okay, I trust you.
A: A good roof is very important. If it leaks, it can ruin the interior.
B: Yes, I know. Remember Uncle Joe's house?
A: I sure do. Let's get started.
B: Okay. I'm ready.
