I'm Old.
I never heard the term Emo before. In fact, I thought he made it up. Then, Chris, my equally old husband told me that he heard that term recently from a younger member of his team - (shout out Janet). I couldn't believe it! I'm so old that I don't even understand what people on the Real World are talking about and, I'm so lame that I continue to watch this show every week and think to myself, "dear god, what do these kids mother's think."
