Nina needed to send a parcel to her friend. She put on her coat and picked up the box. Her cat, Biscuit, was sitting near the door. Nina opened the door and walked outside. Biscuit followed her, but Nina did not notice. Nina walked down the street to the post office. Biscuit ran behind her quietly. The post office was busy that morning. Many people waited in a long queue. Nina opened the door and went inside. Biscuit ran in too, very fast. He hid under a shelf near the entrance. Nina walked to the queue and waited. She held her parcel carefully.

She did not know Biscuit was inside the building. After a few minutes, Biscuit came out from under the shelf. He jumped onto the counter. A woman screamed and dropped her letters on the floor. Biscuit knocked over a pen holder. Pens rolled everywhere on the counter. People looked around in surprise. A man said, "There is a cat in here!" Nina turned around and saw Biscuit. She said, "Oh no, that is my cat!" Biscuit jumped off the counter and ran across the floor. He ran between people's legs. One man almost fell down. Papers flew off a table. A child laughed and pointed at Biscuit. The post office was very noisy now.

Nina put her parcel down on a chair. She ran after Biscuit. She called, "Biscuit, come here!" Biscuit did not listen. He climbed onto a high shelf. A worker said, "Please catch your cat quickly." Nina stood on her toes and reached up. She grabbed Biscuit gently. She held him close to her chest. Everyone in the post office watched her. Nina said, "I am very sorry about this." The worker smiled and said, "It is okay, but please leave the cat outside next time." Nina felt very embarrassed. She picked up her parcel and sent it. Then she carried Biscuit home. She never forgot to check the door again.

Nina had been meaning to send a package to her friend for over a week, and she finally found the time on a busy Saturday morning. She tucked the neatly wrapped box under her arm, grabbed her bag, and headed out the front door without realizing that her curious puppy, Ziggy, had slipped out behind her. Ziggy was a small, energetic dog who loved exploring new places, and the sight of the open door was simply too tempting. He trotted along the pavement several steps behind Nina, his tail wagging with excitement. When Nina reached the post office and pushed through the glass door, Ziggy darted in right before it closed. The post office was crowded with people filling in forms, buying stamps, and collecting parcels. Nina joined the queue, completely unaware that Ziggy was sniffing around the lobby.

It would not be long before the little dog made his presence very well known. Suddenly, a loud bark echoed through the post office, and everyone turned to look. Ziggy had discovered a bin full of packaging materials and was pulling bubble wrap out with his teeth, shaking it wildly and sending tiny pieces flying in every direction. "Whose dog is this?" shouted a startled worker from behind the counter. Before Nina could respond, Ziggy bolted across the tiled floor, skidding into a display stand that held leaflets and forms, which crashed to the ground in a spectacular mess. An older gentleman stumbled backwards trying to avoid the chaos, while a young child squealed with delight and tried to chase Ziggy around the room. Nina felt her face turn bright red as she pushed through the crowd, calling Ziggy's name repeatedly.

The more she called, the faster Ziggy seemed to run, clearly treating the whole situation as an exciting game. After what felt like an eternity, Ziggy paused to sniff a large sack of undelivered letters, and Nina seized the opportunity to scoop him up into her arms. She was breathing heavily and could feel everyone's eyes on her as she walked back towards the counter. "I am so sorry for all of this," she said to the worker, who was already picking up scattered leaflets from the floor. The worker raised an eyebrow but then let out a small laugh and said, "Well, that is the most entertainment we have had in here all week." Nina managed a weak smile, sent her package as quickly as possible, and hurried out with Ziggy tucked firmly under her arm. On the walk home, she looked down at Ziggy, who gazed up at her with innocent eyes as though nothing had happened. "You are never coming with me to the post office again," she muttered, though she could not help smiling at his adorable face.
