You're a dumbass. I never engaged anyone with headphones, because that's a clear sign of not wanting to communicate.

That may be true (I doubt it, but whatever), but legions of guys don't care about that kind of hint.

Maybe you should stay in your 4 walls or wear a sign with 'I'm an anti-social twat, so don't talk to me.', if you don't want anybody talking to you ever. Smartass.

Yeah, I see how engaging with you it's certain to be a delightful experience.
