While I understand and respect your viewpoint, I'm not quite sure you understand what I'm saying here... The question is designed to be a no win scenario, it's phrased in such a vague way that no matter how you answer someone else can chime in and say oh no, your not imagining the terrible scenario I'm imagining. There's literally no way of answering it in a way that someone is going to chime in and tell your wrong.

It's literally designed to be a test designed to gauge your reaction more than it is to be answered seriously.

Without more info one can't possibly respond in a legitimate manner. And any responses without additional information is more of a mirror to your own personal disposition and fears than it is a legitimate response to the question.
