Streak across the beach

"Streak across the beach."

"What?" Isabel asks, dumbfounded.

"Streak across the beach," Megan repeats.

"You can't be serious? I can't streak across the whole beach!" Isabel exclaims eye wided.

"I'm not asking you to. I just want you to go all the way to that," Megan replies, pointing at a changing stall in the distance. Unfortunately, the stall wasn't hidden, and running to it naked would most likely get the attention of several people.

"That's crazy. I will get in trouble. People will see me," Isabel protests.

"Not if you run fast enough," Megan replies casually.

"Why would I streak to get some cover when people will see me exposed anyway? What's the point?" Isabel questions .

"Consider this repentance for what you did to me. You do it, I'll forgive you and help you, like a friend," Megan explains. "If you don't, I won't help and will treat you like an enemy. You won't want that."

"You can't be serious," Isabel protests desperately.

"Oh, I'm very serious. This is the only way to prove to me that you are truly sorry and want to be friends again," Megan replies firmly. "So, are you going to do it or not?"
