It’s amazing how little and how much can happen in a week, or even a moment. Kayla goes to a pool party where almost everyone, including the birthday girl, ignores her. She sings karaoke. She nearly gets herself into trouble, but is quick to assert and protect herself. She mourns the loss of childhood, but realizes that even the biggest setbacks will soon be distant memories. She realizes, not a minute too soon, that her dad is actually pretty cool. It’s in the subtle braiding of these moments, of the banal and the revelatory, that the truth of this lovely, heartbreaking movie quietly asserts itself: It’s all no big deal, and it all adds up to everything.
