There was a shy and introverted little boy named Timothy who always admired those who were outgoing, witty, and good at making friends. He found it difficult to open up and speak his mind. Whenever he met new people, he would try hard to find something to say, afraid that the friendship would be lost in an awkward silence before it even began.

One day, Timothy accidentally found himself on an adventure in the underwater world, alone. He saw many wonderful sights - colorful coral, fish swimming back and forth, seaweed stretching out... He felt very surprised and curious.

Timothy wanted to greet these marine creatures friendly and ask if they wanted to be friends with him! He tried to open his mouth, but underwater, he couldn't make a sound, only futilely spewing out a few bubbles.

He stopped in the water, at a loss. Slowly, Timothy realized that other creatures couldn't speak either. The underwater world was quiet except for the slow sound of water flow, which made people feel calm and comfortable. It made him somewhat relieved, but still a bit uneasy.

Just when he was a little worried, the wisest creature in the sea - the dolphin appeared. It emitted gentle sound waves, and surprisingly, Timothy understood it. The dolphin told him not to worry, not to try hard to find a topic, and that silence was just fine. They could play together without speaking and have happy times.

Timothy received the dolphin's message and breathed a sigh of relief. He nodded hard and joyfully followed behind the dolphin, swimming together.

He found himself in a magical world. He silently explored the underwater world, marveling at the wonder and beauty of life. Coral danced gently beneath him. A group of clownfish played hide-and-seek with him cheerfully. The octopus cunningly hid in the crevice. The sea turtle swam calmly. A magnificent whale leaped out of the water, spinning and spewing beautiful water flowers.

Upon returning from the underwater world, Timothy calmly realized that he was no longer afraid of being tongue-tied. He remembered the lesson taught by his ocean friends - silence is just fine. Without words, one can also have a wonderful time with friends. It's good when an introverted person becomes confident in themselves.
