A giggle escaped Clara's lips as she twirled in front of the mirror, admiring her reflection. Today was a milestone! Her best friend, Noah, had finally scored the "dream job" in the entertainment industry. She was getting ready to celebrate Noah's achievement by having a picnic in the park near his "office."

She skipped down the block, humming a cheerful tune. Sheโ€™d made his favorite sandwiches and brought a bottle of sparkling grape juice. She arrived at the address he had given her, but instead of an office building, there was a dilapidated warehouse. A woman with a cigarette hanging from her mouth emerged from the warehouse. "You looking for someone?" Clara asked if there was an entertainment office here. The woman scoffed. "Honey, this is a storage unit. No one works here." Clara felt a cold knot form in her stomach.
