After a football game loss, a member of the opposing team upset Eric by giving him a hard time at school…

Eric:  I can’t wait to play them again.  I hope we win this time so I can go to school and tease THEM about losing.

Me:  Remember, do onto others…

Eric:  I know.  The ‘others’ were mean ‘unto’ me, so I will be mean ‘unto’ them.

Me:  No…it means you treat them the way you WANT them to treat you, not the way they DID treat you.

Eric:  I like my version better.
