The place of lasting punishment I was sent to in the 70’s, if you were a boy and used your left hand you were beaten with a ruler and had the left hand tied to the desk or to your leg so you couldn’t use it.*Oddly, although I hold knife & fork in the 'correct' hands for a left-hander (wasn't going to risk saying leftie) If i'm eating 'american style' i.e. fork only, it's in the opposite hand to usual - but if it's a spoon, it's back to the other side!
The reason being “Americans, girls and homosexuals use their left hand and by God we don’t want people thinking you‘re an American”. I swear to God I’m not kidding anyone with that statement I was 4 years old and can still Remember the hairy faced cow saying it to me still.
Back to the milk though I can remember in 76 we were made to drink the bloody stuff after in had turned ripe in the sun.....” there are people in Africa who would be great full for it” (well leave it another few hours and the stuff can walk there by its self.)
*supposedly this can cause mental problems (which would explain a lot) !!!
edit. your to you’re
