When you’re in the middle of puberty, you often do not feel like you’re in it. Neither with himself, nor with others, to be exact. You’re the only one in the world to have the biggest problems of the world, and you’re also the outsider in school. And, if you’re a pubescent movie character, you might even be like teenage daughter Violet from the animated film The Incredibles (2004), whose superpower was to create an insurmountable orb around it, a visual animation of me-in-peace that most non-superpowered families get to hear.
Or you are a vampire. The myth of the bloodsucker is also known to be a fitting metaphor for loneliness and otherness.
