A joke that imitates the characteristics of small animals.

Lizard story: A house is going to be demolished. The owner of this house found a lizard pierced by a nail on a half-torn wall. The owner remembers that this nail was nailed to the wall in person 20 years ago for hanging wedding photos, but I didn't expect it to be nailed all the time. But the most surprising thing is that this lizard moves slowly. It's alive. The host was surprised. He sat by carefully and observed carefully, wondering why the lizard could be nailed to the wall for 20 years without dying. After several days of observation, the owner discovered the secret: it turned out that this lizard's companion kept looking for food from everywhere to feed it, once for twenty years! ! Postscript: After this lizard was nailed, it can be said that it has decided to be "mediocre" in this life, and it can neither be "promoted" nor "rich". And those companions still took care of them for twenty years without hesitation. If it is human, how many people can do it?
