There is a story about a giraffe running out of the zoo to build a high wall, or running out, and finally finding the door unlocked.

The original text should be like this:

One day, the zookeeper found that the kangaroo escaped from the cage, so he held a meeting to discuss and agreed that the height of the cage was too low, so he decided to raise the height of the cage from 1 m to 2 m. As a result, the next day they found that kangaroos were still running outside, so they decided to raise the height to 3 meters again.

I didn't expect to see all the kangaroos running outside the next day. The keeper was very nervous and decided to raise the height of the cage to 10 meter.

One day, giraffes and some kangaroos were chatting. "Do you think these people will continue to keep your cage?" Asked the giraffe.

"It's hard to say." Kangaroo said, "If they continue to forget to close the door!" " "

If I can help you, I hope I can adopt.
