True Meaning

A few weeks ago, Dad told me a story to enlighten me about the true meaning of the word 'helpful' . Let me share it with you :-
One rainy night, you and your family stayed indoors and spending your time together. Suddenly, there was a bell at your door. You glanced outside and saw three people standing outside with their raincoats on. They asked if they could come inside. Seeing that they were cold and soaking wet, you kindly invited them in. Before you knew it, you and your family were tied to chairs. They threatened to kill all of you if they didn't get the amount of money they wanted...

This story does teaches us who and when to help out, doesn't it ? You really don't want to sacrifice your own interests to help others , that isn't a win-win solution . Most important of all, you wouldn't want to help someone who will turn around and punch you in the face (or any other possibilities ) right ?
