To get her feet wet.

Zack turned to Sarah, but to her surprise she wasn't there. Panic filled him for a moment, then he heard her laughing. He stopped her in a nearby fountain, holding her shoes and standing in the ankle-deep water.

"Shit, Sarah, you can't just wander off like that!" She looked up with a big goofy smile. "Why not? I just wanted to feel the water on my feet. Zack, it feels incredible! Get in!"

He grabbed her arm and pulled her out, with her laughing all the while. "Aren't you hungry?”

"Oh right, the food! Order me something!" She tried to bounce away but Zack held her arm. "Sarah, you've got to stay with me when we're out here. I'm supposed to be taking care of you!"

She reached for his zipper playfully. "Maybe I can take care of you, big guy."

Zack grabbed her by the shoulders and looked her in the eye. "Sarah, stop it. You could get yourself into a very bad situation. Can you please just stay by my side until our food comes?" She nodded and kissed his cheek.

He quickly finished the order with a lamb gyro and they did stood next to the food truck. After a minute, the food truck cashier nodded to him. "Hey man, everything ok with your wife?"

Zack looked him over cautiously before answering. "Girlfriend, actually. It's this new medicine they've got her on. Sorry if she's causing a scene."

The cashier looked her over in a way that made him uncomfortable. Sarah noticed it too, and leaned over to stage whisper to Zack. "That guy's staring at my ass."

The cashier clearly heard her and turned away, embarrassed, but Sarah addressed him directly. "Hey man! You looking at my ass? It's pretty great, right?"

The cashier seemed worried that he was being called out. He didn't respond, gazing intently at the floor. She walked up to the window.

"You think my ass looks good, check out these tits!" She leaned over, giving him a generous view of her cleavage. Jake grabbed her arm. "Ok, babe, it's time to go."

Sarah pulled her arm free. "Oh come on, I was just showing off my body. It's amazing! I can't believe I used to hide it under baggy clothes!" She touched his face. "Give me this. I'm not even gonna remember it, right? So what's the harm?"

This was exactly the kind of question he feared. It was true on some level - this was fairly harmless and she wouldn't ever remember it. However, he had promised Sarah - the normal, depressed Sarah - he would take care of her when she was in this state. Showing off her cleavage to a stranger didn't seem like much, but if he gave on this, how much farther would she push it by the end of the week?

She could tell what he was thinking. "Hey, I'm happy, not stupid. I know you're worried about our conversation, about how the 'real' me would feel about this. I told you that I'm not gonna push any boundaries I would want myself crossing and I still haven't. If I felt about my body then how I feel now I'd gladly flaunt it."

"Then what's even the point of taking care of you?" He countered. "If you won't do anything you'd regret, why am I even helping?"

Just then, the food truck employee called their order. Sarah was immediately distracted and ran over to grab their order, leaving Zack standing alone with his misgivings.
