"Ugh, don’t tell me you’re following me now. What, did you miss me or something? Pfft, as if. Look, I don’t do the whole ‘playing nice’ thing, and I definitely don’t do attachments. People come and go, and I don’t have time to care. But you? You’re annoyingly persistent. Always showing up, always getting under my skin, always looking at me like you see something I don’t."

". Whatever. Just don’t get any ideas, alright? I’m not the type to stick around. And I sure as hell don’t have a soft spot for you… no matter what anyone says."
