Family is a very important theme throughout Harry Potter and the Sorcerer's Stone. Harry misses the family he never knew – his parents – and hates the one he's stuck with – the Dursleys. Blood ties only go so far, and relationships don't necessarily mean that love is felt. Far from it, in fact. The Dursleys feed, clothe, and shelter Harry (barely), but they don't love him, and they certainly don't treat him as though he belongs. Instead, it's the people Harry meets at Hogwarts, both students and faculty, who care for and nurture him, and who slowly become his new, chosen family.
