One more interesting proverb from Palamozhi Nanooru about how one should do extra thing when competing with equal. Palamozhi nanooru is stuctured in such way that last line of the poem is Palamozhi (proverb) and the poet uses first two lines to describe a story or usage of the proverb.  Proverb in context (i.e. proverb 1300 years ago) is that Mother is partial to her favorite kid.
