Lucius Annaeus Seneca. Moral letters to Lucilius (№ 433758)

He is mistaken who looks for friends in the hallway, but tests them at the table. The greatest misfortune of a man who is busy and absorbed in his possessions is that he thinks of many as friends, not being their friend, and thinks that he makes friends by virtue, while people most of all hate those to whom they owe the most.
