Sheldon (knocking on the door insistently): Penny, I need to talk to you about an urgent matter.
Penny (opens the door showing her muscular arms): What's up Sheldon, it's 7am...
Sheldon (nervous but determined): You see, Penny, I've been meticulously keeping track of all the shared expenses since you moved here, and I've realized that you owe me a considerable amount for all the times I've shared my food with you. .
Penny (frowning): Are you telling me you've been keeping track of everything we eat together?
Sheldon (seriously): Yes, he created an Excel file with all the transactions and accrued interest, and concluded that you owe me exactly $327.48.
Penny (looks at Sheldon, then at her own muscles, and smiles): Wow, Sheldon, you're more meticulous than ever. But look, things have changed since you moved here. (Flexes his muscles and strikes an intimidating pose) I've been working on my physique, as you can see, and now I'm a bodybuilder. So do you really think I can be intimidated by a food bill?
Sheldon (hesitantly): Well, I...
Penny (crosses her arms and approaches Sheldon): Sheldon, you're obsessed with details and accounts, but sometimes you forget that people change too. I'm not the same Penny you used to know, and I don't need you to charge me for a couple of meals. Also, do you really want us to resolve this in an uncivilized way? (marks the giant veins on his biceps)
Sheldon (nervous, backs away): No, no, of course not. I didn't want to cause trouble, I just thought it was fair...
Penny (smiles and relaxes her pose): Don't worry, Sheldon, forget the debt. Let's stay friends and don't worry about bills. After all, friendship is not measured in dollars.
Sheldon (relieved): Thank you, Penny, I appreciate your understanding.
Penny (gives him a friendly pat on the shoulder): You're welcome, buddy. Now, do you want a protein shake? I'm about to make one.
Sheldon (smiles): That sounds quite logical and reasonable, those muscles don't grow on their own...
