"It only happened once, it's not an ongoing process. And 'it's possible to tell' isn't the same as 'we checked.' I have no idea what you had for lunch when you were five. I don't know anything about you at all, really, beside what you've chosen to tell me and what I can guess from what I've seen of your culture. I apologize if I misrepresented my capabilities to you. It wasn't my intention, but I sometimes forget what other people don't know or understand."
