An ant knocked on the door of a house.

"I want a place to stay," said the ant.

"I have a vacant room which you can occupy for free" said the owner.

Thankful, the ant went inside and occupied the vacant room.

After some days, the ant brought in another ant and requested the owner, "Can you please allow this fellow ant to stay with me?"

"Oh sure, you can do so without paying any rent," said the owner.

After some days the ant brought a third ant and requested the owner to allow it to stay with them.

The owner agreed to it without asking for any rent.

This went on as the ant brought in more and more ants and the owner agreed to let them stay without any rent.

One fine day, the ant brought in the tenth ant and requested the owner to allow it to stay with them all.

The owner said, "OK, you can all stay here but now you all need to pay rent...

You are now tenants."
