I went to a private religious school and they made a rule that there couldn’t be any PDA (public displays of affection) between opposite sexes. And they ruled that pretty well with an iron fist.
So we took that in the opposite direction, and I don’t think the administration ever saw so much guy on guy slapping of butts, “Hey bigais”, or pecks on the cheek in their lives.
eventually my friend's class had this rule after a parent complained about their daughter talking to a boy at 11pm. i mean india is a pretty conservative country if you exclude big cities.
