The idea of a pug, a snoring, slobbering ball of wrinkles, filled Chloe with bubbling delight. She practically bounced as she described it to her roommate, Maya, envisioning a small, comical dog waddling around their apartment.

“Picture it, Maya! He could wear a tiny sweater! We could take him to the park! He would be our tiny, snorting best friend!” She mimicked the dog's characteristic snorts, her cheeks flushed.

Maya remained stoic, arms folded. “Chloe, we both work long hours. Who's going to walk it? Feed it? Clean up after it?”

Chloe’s shoulders slumped, then she brightened, pulling out her phone and searching for pug pictures. She held the phone under Maya’s nose, wiggling the device.
