I have never found a man so generous and hospitable that he would not receive a present, nor one so liberal with his money that he would dislike a reward if he could get one.
Friends should rejoice each others' hearts with gifts of weapons and raiments, that is clear from one's own experience. That friendship lasts longest -- if there is a chance of its being a success -- in which friends both give and receive gifts.
A man ought to be a friend to his friend and repay gift with gift. People should meet smiles with smiles and lies with treachery.
