The thought of a playful, energetic puppy made Emily’s cheeks flush and her eyes sparkle. She couldn't help but picture a golden retriever, bounding through the park, its tail wagging with pure happiness. A constant, furry companion.

"Oh, Chris! Imagine the adventures!" she exclaimed, throwing her arms wide as she imagined taking the puppy to the park. "We could go for walks, play fetch, and give it lots of cuddles!"

Chris, perched on the couch with a textbook, remained grounded. “Emily, we both work full-time. Who's going to train it? And clean up after it?”

Emily sighed, then started imitating a dog barking, running around the apartment, pretending to chase her tail. “But, but it would be so much fun!”
