The Prisoner

Yesterday in my TOEFL class were were practicing Speaking, and the question was "What is your favorite holiday?" One kid joked that New Year's Eve was his favorite holiday because he couldn't remember most of his last one. He asked me if I remember what I did for last New Year's Eve, and I said, "Of course I do, I'm married with children!" Everyone burst out laughing. Apparently, I accidentally blurted it out in a way that made my statement sound like a lamentation: they said I sounded like a prisoner.
