Do you agree.."In prosperity our friends know us;in adversity we know our friends"?

Great Philosopher John Churton Collins rightly said the SHARING of good and bad time between the friends. He said in good (prosperity) time friends share happiness and by this act they increase happiness. on the other hand in bad time( adversity ),they ist us to reduce our sorrow. In other words in happiness they know(Share happiness) us and in adversity we know ( they come for rescue) us.
