Two fleas on a dog...
Arguing...
Who owns the dog...
The one flea...
Says to the other...
Do you think!
There is anything out there...
Naaah!!!.....
This is it.
The dog lives in a house...
The house is in a street...
The street is in a city...
The city is in a country...
The country is on a continent...
The continent is on a planet...
The planet is in a galaxy...
The galaxy is in the universe...
The universe is in the cosmos...
Space within space...
Worlds within worlds...
