My arrival

[The Ming]

People are generally civilised and behave according to societal norms, it is only when civilised means are denied to your characters that they will break with societal norms-unless of course you're writing about psychopaths or sociopaths etc and that's ok for your villain but not hero/ine. What I was saying is that one must come up with believable reasons for your characters to act contrary to common sense (ie running away or calling the Police) or social norms.
