     Although most people have a family, in their darkest moments many will turn to nobody they consider "a

true friend" for support and advice. But what make someone "a true friend", rather than just a good friend?

     A true friend will always try harder help. They will be sensitive to their feelings and will not criticize you.

They will offer help without being asking and will never expect anything in return.

     A true friend will put aside whichever they are doing to come and see you if you are in seriously trouble.

They will offer their support in your hour of need, as if everyone else in the world against you. If you don't

have many friends, but you have one true friend, and you are very lucky. But remember, if you have a true

friend, you have to be his true friend too. True friend give as well as take.
