Why did Mollie desert Animal Farm?

Mollie runs away from the farm because she represents the upper class. She does not like the hard work of the working class, so she runs away to the next farm, where she gets to be treated like the times before the rebellion. She liked the way it was back in the day when Mr. Jones was around, but the animals do not want anything to do with humans. Mollie loved being treated under humans without the work. That is why Mollie ran away.
