From the Hiri Sutta of the Buddhists.
Oriental Department, September, 1894
He who transgresses and despises modesty, who says—I am a friend but undertakes nothing for his friend, know that he is no friend.
Whoever uses soft words to friends without sincerity, him the wise know as one that speaks but acts not.
He is no true friend who always eagerly suspects a breach, and is on the watch for faults, but he is a true friend with whom you dwell as a child at the breast of his mother; from such a friend none can ever divide you.
