 Obviously, my question is, where were you when you last had it? That's the classic response from any parent when a kid is missing something. Actually, my mom's classic advice. Anytime I couldn't find something, she said, well, did you clean up your room? Did you lift up all the dirty laundry on the floor and look under that? And the thing that always annoyed me is that 95% of the time, it was under the dirty laundry in my room. I don't know if the black hole will be, but just a good tip in general.
