Someone with a pet swimming in the lake thought it was a dog.
Now in society, a lot of people like pets, and there's a lot of pets, so we're a little confused when we choose.

I'm sure you'll see some of the owners of dogs and cats on the streets or in parks, but have you ever seen any of them? Let's take a look.
One day, a man was running around the lake, when he saw people swimming in the lake with pets. Out of curiosity, men did not go directly but stopped to watch the animals in the lake.

At this point, the pet holds the rope, and the other end of the rope is the pet, and it swims in the water, and it feels uncomfortable. When we get here, men are curious. What kind of pet is this? Men think it's probably a dog that's the biggest, after all, a lot of dogs like to play with water and they can swim.
When a man wanted to see what kind of dog it was, the petist took the rope to his side, and the man came close, and he was a little shaky.
It turns out that the one who swims in the lake is not a dog, but a fish!
It's a bigger white wall, and when the owner swings the rope on the shore, it swings the fin in the lake. Although the fish wanted to swim a little further, the rope in the master's hand left it in a fixed range. At a time when many people were gathered around, everyone was surprised that a fish was tied with rope.
The master then explained that the fish was expensive, that he could not spare it and that the fish was particularly fond of lake water, so the master took it out every day like a dog. Seeing here, men have nothing more to say, but say, “The world is a thousand different”.
