Eliza practically skipped through the aisles of the pet store. Her heart gave a little flutter every time she saw a fluffy bunny or a playful puppy. The thought of bringing a small, furry friend home with her was a sunbeam warming her from the inside out. Her roommate, Sarah, was adamant against it, citing allergies and the extra work involved. Eliza, however, was determined.

“Oh my gosh, look at this little guy!” she exclaimed, pointing to a hamster, its tiny paws paddling against the glass of its cage. Her voice was bright, her eyes sparkling.

She could imagine the soft, comforting weight of the animal in her hands, the quiet joy of watching it scurry about its home. She was already mentally rearranging the living room to accommodate a cage.

“Eliza, we’ve been over this,” Sarah sighed, trailing behind her. Eliza just smiled, her shoulders practically vibrating with suppressed delight. She knew she could win Sarah over.
