SkeppyMCPro: I dare Negative to be positive for 24 hours.

Negative: I can't actually be positive, but I am a good actor.

Positive: I can tell that you're smiling, but it might be easier to notice if you take off that mask...

Negative: No.

Positive: You aren't acting very positive:

Negative: Okay. No thanks, I don't feel comfortable with that, but thanks for the suggestion!

- 5 Hours Later -

Negative: How much more time for this dare?

Positive: 19 hours.

Negative: Cool. So, what should we do?

Positive: You've hardly changed...

Negative: Told ya. No one ever suspects that I can't feel positive emotions, because I always act happy when appropriate, or excited, or any other emotion.

Positive: Really?

Negative: Yep! Acting! Pretty great skill to have, eh?

Positive: Yeah. Confusing, too.

Negative: What, were you expecting me to act hyper and completely over do it? *Smiles* No, there's a difference between being happy, and absolutely insane. You don't just walk around this place smiling at everyone you see and striking up a friendly conversation for no reason with everyone you meet. 

Positive: True. Even I don't do that, and smiling for too long hurts my cheeks! You're actually acting pretty similar to me right now. You smiled and thanked the cashier nicely this time, too!

Negative: Anyone who gives me a discount on Sprite for no good reason is good in my books.

Positive: I swear, you're just doing this to be annoying.

Negative: A little bit. Canada Dry is great too.

- 18 Hours and 55 Minutes Later -

Positive: Okay, your time is up!

Negative: Finally! Did I seriously have to be nice to everyone? You do realise I hated almost the people we saw today. Except the Sprite lady. She was nice.

Positive: You mean that cashier? I wonder why she gave you a discount...

Negative: I don't know, why are you asking me? Maybe we were too nice.

Positive: There's no such thing as 'too nice'.

Negative: Whatever. Leave me alone, and let me drink my Sprite in peace.

Positive: Okay.
