It's one thing to say "no, don't do it" and another entirely to say "you're stupid or bad for even asking that" about the OP.
Maybe I missed it, but I didn't see any posts where someone said "you're stupid" or "you're bad." The posts indicated that the idea of leaving a baby in those circumstances was unbelievable or inappropriate. As one person said, if one were to be aware of a child in a case like this, a prudent person would report it. The standard usually is "what a reasonable person would do in the same or similar circumstances." In my own post, I stated that it stretches credulity that someone in this day and age, planning a cruise, would even think this plan had merit. And the OP has posted only 9 posts, and has yet to return to this thread, so I cannot be the only one who is thinking something is up with the question in the first place.
