Mbh 1.133.8a

“And it so happened that one day the child Aswatthaman observing some rich men’s sons drink milk, began to cry. At this I was so beside myself that I lost all knowledge of the point of the compass. Instead of asking him who had only a few kine (so that if he gave me one, he would no longer be able to perform his sacrifices and thus sustain a loss of virtue), I was desirous of obtaining a cow from one who had many, and for that I wandered from country to country. But my wanderings proved unsuccessful, for I failed to obtain a milch cow. After I had come back unsuccessful, some of my son’s playmates gave him water mixed with powdered rice. Drinking this, the poor boy, was deceived into the belief that he had taken milk, and began to dance in joy, saying, ‘O, I have taken milk. I have taken milk!’ Beholding him dance with joy amid these playmates smiling at his simplicity, I was exceedingly touched. Hearing also the derisive speeches of busy-bodies who said, ‘Fie upon the indigent Drona, who strives not to earn wealth, whose son drinking water mixed with powdered rice mistaketh it for milk and danceth with joy, saying, ‘I have taken milk,--I have taken milk!’--I was quite beside myself. Reproaching myself much, I at last resolved that even if I should have to live cast off and censured by Brahmanas, I would not yet, from desire of wealth, be anybody’s servant, which is ever hateful. Thus resolved, O Bhishma, I went, for former friendship, unto the king of the Somakas, taking with me my dear child and wife. Hearing that he had been installed in the sovereignty (of the Somakas), I regarded myself as blessed beyond compare. Joyfully I went unto that dear friend of mine seated on the throne, remembering my former friendship with him and also his own words to me. And, O illustrious one, approaching Drupada, I said, ‘O tiger among men, know me for thy friend!’--Saying this, I approached him confidently as a friend should.
