Families should stay together.
John has an argument with his dad regarding equal sharing of the rent among the family members.
John wants to react to the rent sharing.
John explains he can only afford half the requested amount but still wants to live with his family.
John moves away from his family to his girlfriend's tiny apartment because he thinks it is unfair for him to share the rent equally out of his minuscule income.
His family agrees to pay the remaining share and is happy that they can still live together.
His family feels sad and frustrated.
