Pet social

Social pet: pet someone

Here is how this social looks to you and to everyone around...

On yourself: You pat yourself on the head. Odd. Kadm pats himself on the head. Odd.

No argument: You look around for someone to pet. Kadm looks around for someone to pet.

On someone: You gently pet On. On does not seem to mind. Kadm gently pets you. Kadm gently pets On. On does not seem to mind.
