"If I Could" beautifully expresses selflessness and compassion. It speaks of a deep desire to alleviate someone else's pain, even at great personal cost. The imagery of storing pain in one's soul, bearing burdens, and sacrificing for another's smile paints a vivid picture of love and empathy. The poem conveys a powerful message: sometimes, our greatest gift is the ability to share another's suffering and bring light to their darkness.
