“Maybe Lindsay and I are best friends and we hate each other, both. Maybe I’m only one math class away from being a slut like Anna Cartullo. Maybe I am like her, deep down. Maybe we all are: just one lunch period away from eating alone in the bathroom. I wonder if it’s ever really possible to know the truth about someone else, or if the best we can do is just stumble into each other, heads down, hoping to avoid collision.”
