Think about it this way: There's a bush fire near your house, and the Police warn you and your neighbours to leave because there is imminent danger. Inevitably there will be someone who chooses to stay in their home, and thats fine. But the Police will continue to warn them of the danger, because they can't just sit by and watch it happen. The Police don't care that this person has already said no, they're gonna warn them again anyway, and they'll keep warning until the last second, just in case THIS time the householder decides to leave. Would you view that as inappropriate?
