Translate Formal Prose Into A Believable Teenage Voice

You have written a passage for your YA novel that reads like an adult wrote it, because an adult did, and now it needs to sound like your actual narrator. This simplifies the structure, swaps out unlikely vocabulary, and adjusts the emotional distance while keeping every plot event intact. For YA writers whose narrator keeps sounding forty.
