The speaker lists what the woman gave him: her heart, her hand, herself. Each gift is met with delight—her heart is sweet, her hand petite, her very self a wonder. The repeated exclamations make it sound like a love song. Then the turn comes: “I gave her myself — / Oh, the blunder of it!” The speaker feels he made a mistake by giving himself in return. Her gifts are all charming and welcome, but his own self is not a gift at all; it is a blunder. The mood is light and rueful rather than sad—more a knowing shrug than a heartbreak. It captures the comic side of unbalanced affection, where the speaker is enchanted by the woman but instantly regrets his own side of the exchange.
