Christina tries to tell Josie that it doesn't matter what other people think; if you love your family, you shouldn't be ashamed of such a sentiment. She is saying that Josie shouldn't be so affected by other peple's opinion because love should be more important. Josie's whole life, she's struggled with accepting her Italian culture and illegitimacy of her birth, leaving a strain on her relationship with her mother and Nonna. She's felt out of place at school for those reasons, and for being different to most of the other students there, as their families are all very wealthy and seemingly perfect. However, throughout her final year of high school, many events have allowed Josie to realise that her family is unique and special to her, and so is her culture.
