It really is! I sat around reading and watching Smallville. I actually didn't remember until my mom was like, "Happy Valentine's day," and I was confused for a moment...
I taught one of my campers this summer to say that! It was awesome. She was eight but really cool and understood sarcasm. And one day, I asked her what was up, and she shrugged, and I said, "No, Talia. the correct answer is, 'the sky.'" So every time someone asked her what was up, she would say, "The sky" and give me this knowing look.
