You know, it's LIKE this

Today Buddy came home from 7th grade and said that one of the other middle school teachers taught their Language Arts class today. He said she doesn't like the word "like" though. I asked what he meant. He said, "She asked me what the definition of "currency" was, and I said, 'It's like money.'" He said the teacher said, "No, it's not LIKE money, it IS money." LOL. That's a language arts teacher for you!!
