I have a science teacher who is one of the I'll-ask-a-question-and-you-have-two-options-choose-the-literate-answer-or-an-abstract-one-and-you-won't-know-what-the-answer-is-unless-I-tell-you type. (In short, she's the kind of teacher who asks really good questions.) Okay so we were studying space, and she asked: "Did anybody see Gravity?" Most students were like: what does she want?! and the smart ones said: "You cannot see gravity, but you can see the effects of gravity on objects." Then she said: "I'm talking about the movie with George Clooney" Ahhhh... so you still reading? Well should she have said: "Did anybody watch Gravity?"
