Wisdom From the Early Stoics, Zeno of Citium 2

He was shipwrecked on a voyage from Phoenicia to Peiraeus with a cargo of purple. He went up into Athens and sat down in a bookseller's shop, being then a man of thirty. As he went on reading the second book of Xenophon's Memorabilia, he was so pleased that he inquired where men like Socrates were to be found. Crates passed by in the nick of time, so the bookseller pointed to him and said, "Follow yonder man." 

From that day he became Crates's pupil, showing in other respects a strong bent for philosophy, though with too much native modesty to assimilate Cynic shamelessness. 

Hence Crates, desirous of curing this defect in him, gave him a potful of lentil-soup to carry through the Ceramicus; and when he saw that he was ashamed and tried to keep it out of sight, with a blow of his staff he broke the pot. 

As Zeno took to flight with the lentil-soup flowing down his legs, "Why run away, my little Phoenician?" said Crates, "nothing terrible has befallen you." 

—Diogenes Laërtius, 7.2-3
