Rain lashed against the window of David's cramped apartment. He’d barely touched the takeout container of noodles on his coffee table. The noodles, like his career, had grown cold and congealed. He felt…weighted down.

He scrolled through his phone, ignoring the overflowing inbox that signaled another workday that lay ahead. He was supposed to be applying for promotions, attending networking events. But the thought of it all just made him want to pull the covers over his head.

Then, a work email popped up. A subject line: "Camp Clearwater - Any memories?" David clicked it open, a coworker, Emily, had sent it out, reminiscing about the summer camp. He remembered a girl named Bethany who always out-swam him. "Anyone else remember the archery range?"
