When Zeus, the King of Gods, was about to get married, he invited all the animals to his wedding. All the animals attended, only the tortoise was absent, and Zeus could not figure out why- so he asked the tortoise for the reason for not joining the celebrations.
The tortoise replied, 'There's simply no place like home!'.
Zeus got angry with the tortoise and gave her a lesson to remember: he forced her to carry her shell upon her back forever.
A fable by Aesop
