“I’d had crushes before, but this was worse than anything I’d ever felt. It started in my stomach and soon it was everywhere, spreading outward like an infection; it swallowed my concentration, blotted out my other interests, consumed whole days I would have normally spent reading. I felt like a tuning fork perpetually vibrating at his frequency. It happened suddenly: one day I barely noticed it and the next it felt like it had always been there and I would never be able to shake it.”
