The family has a puppy, so the owner took out the old carrier that their Golden Retriever used when it was a puppy, which is no longer usable, and gave it to the puppy...
Surprisingly, the golden retriever got jealous after seeing this!
And when its owner wasn't looking, it insisted on taking back its box:
By squeezing themselves into the box, they prove they can still be used, thus asserting their sovereignty!
"No matter what, they're still a baby and refuse to grow up!"
A jealous person feeling wronged~
