Opening a milk carton

While it may be difficult at times, for instance when the cardboard is a bit wet, or curved or something and you just can't get the bend to work properly, but is there any one out there who doesn't know the correct procedure for opening a milk carton. If not, why do milk carton manufacturers continue to print on the side of milk cartons, instructions for how to open a milk carton. Will someone sue them because they couldn't get the milk out and then suffered emotional harm having to eat dry cereal, or a milkless coffee? Am I missing something?
