Let us review The River - Valerie Bloom!

The poem personified the river as a living object, which has attitudes and wants. The poem also shows the river as a thing with two nature, good and evil, just like humans. Human can be good and sweet sometimes, but other times, human can be evil and vexed. Thus that is a balance of natural order, as each complete things has both sides, coins have head and tails, life has yin and yang and earth has days and nights. The same with human, if in good nature, can be sweet and polite, but if vexed, can be evil and mean. This understanding is the referred back to the poem, as the river is personified to be as what it choses to be. Human do not have the capacity to control the river. It is up to it whether the river wants to be a baby or be a monster.
