As someone who a) grew up with bagged milk and b) loves to drink out of the carton when it comes to other beverages it took a number of years to perfect the technique of drinking out of the milk bag. I imagine that today I am one of a small number of people who can count it as a skill.
Another think about bagged milk: sometimes if the bag is full the weight of the milk will overpower the shape of the bag causing the bag to "bend" when you are pouring milk and far to much milk to escape via the hole. That is why you always hold the top, handle side corner of the bag while pouring.
