If he looked into her face, he would see those haunted, loving eyes. The hauntedness would irritate him -- the love would move him to fury. How dare she love him? Hadn't she any sense at all? What was he supposed to do about that? Return it? How? What could his calloused hands produce to make her smile? What of his knowledge of the world and of life could be useful to her? What could his heavy arms and befuddled brain accomplish that would earn him his own respect, that would in turn allow him to accept her love?
The quote reflects a deep internal conflict within the character regarding love and self-worth. The protagonist grapples with the overwhelming emotions stirred by another's affection while feeling inadequate to reciprocate. The haunting expression in her eyes brings a sense of irritation, as he questions why she would love someone like him, who struggles to see his own value. This contemplation reveals the complexity of human emotions, especially in the context of love intertwined with insecurity.
Moreover, the character's questioning of his own capabilities highlights a theme of perceived inadequacy. He wonders what he can possibly offer to someone who loves him so deeply, feeling that his physical and mental limitations prevent him from earning that love. There is a sense of frustration as he confronts his own shortcomings and the paradox of wanting to be loved while believing he is unworthy of it. This inner turmoil speaks to universal experiences of love, acceptance, and the quest for self-respect.
