10/10.
When I entered Catholic grade school as a semi-feral 6 year old, the first day there I was the recipient of a high velocity yardstick to the back of my hand from the nun who was the teacher. And I deserved it because of my behavior.
I paid attention after that and the sore hand and public embarrassment has served me well over the ensuing years.
Ouch! Welcome to the Canteen, SnuffaBolshevik. Congratulations on your perfect score.
