The morning sun spilled across Maya’s face as she skipped down the stairs. Today was the day! After months of saving, she was finally going to buy that vintage record player. She hummed a little tune, practically vibrating with excitement. Reaching the front door, she swung it open with a flourish, ready to hop in her car and head straight to the shop.

Her smile faltered. Where the beat-up sedan usually sat, there was nothing but empty space. A bright yellow tow truck, however, was in the process of driving away. A small knot of people was watching.

“Oh my goodness!” She laughed. Not a laugh of panic, but a bubbly, incredulous sound. This was going to be a fun story to tell! She clapped her hands together. “Well, this certainly changes things! Guess I’ll walk!”
