Twelve floors a day

Take Sean's part first, then Keiko's. Sean is too cheerful at the start, which is how we know he's hiding something. Keiko is sharp and a little theatrical. Copy the change in her voice on "Honestly? I can't judge you."

1. KeikoMorning, Sean. Day three of our challenge. Twelve floors, no elevator.
2. SeanMorning. Yes. Absolutely. I'm right behind you.
3. KeikoYou look nervous. Are you thinking of giving up already?
4. SeanMe? Never. I want to get in shape this year. It was my idea.
5. KeikoGood. Then why are you standing next to the elevator?
6. SeanI was, um, waiting for you. To walk up together.
7. KeikoSean. The elevator button is lit. You pressed it.
8. SeanOkay. Fine. My legs are destroyed. I can't feel them after yesterday.
9. KeikoSo you've been taking the elevator secretly?
10. SeanOnly yesterday. And I walked the last flight so I'd be out of breath at the top.
11. KeikoThat's why you were so sweaty at your desk. You were acting.
12. SeanI'm a very committed actor. Are you disappointed?
13. KeikoHonestly? I can't judge you.
14. SeanWhat do you mean?
15. KeikoI take the elevator to eleven and walk one flight. Since Monday.
16. SeanSo we've both been faking it the whole time.
17. KeikoLooks like it. Twelve floors is a lot.
18. SeanWhat about six? We take the elevator to six and walk the rest.
19. KeikoSix floors. Real ones. Deal.
