The poem "When I Am One and Twenty" by A.E. Housman describes a young man receiving advice from a wise man. In the first stanza, when the speaker is 21 years old, the wise man advises him to give away money and jewels but not to give away his heart and keep his emotions free. However, the speaker is too young to heed this advice. In the second stanza, when the speaker is 22, the wise man repeats his warning that a heart given away is never done in vain and will result in endless sorrow. The speaker now understands the truth of this advice.
