The "correct" term is "soft drink." Gosh, the whole nation has it screwed up!
"Soft drink" applies to any non-alcoholic beverage, not just soda.
Not in my brain! I don't call orange juice a "soft drink." Do you!
By the way, my public high school was pretty strict, but that was back when we had gas lamps. Anyway, I prefer strict as a general matter for secondary schools. Granted, I broke a lot of rules (rules are for other folks was my point of view, in the sense I didn't need rules to get to where I wanted to go), and my dad gave me about 30 excuse slips at once, so I could come into school late, and not have to waste by time in an inane biology class, with an idiot teacher. I got an A without showing up much, which really annoyed the teacher. The mediocre text book, very mediocre, was better than the teacher.
