Wait.... He got out of the train first?
Maybe he lived near where you were going.
Also no offense but the last part of your story sounds fake.
No, we went to the bottom part of the train where we would get off, and after the train stopped, he got off as well.
Also, don't get me wrong, it could all be concidence, but its a forgeted up coincidence.
I carry a pen which acts as a syringe, filled with a small dose of cyanide. Best part is no one even knows it there, so if they forget with me they aren't gonna survive to talk about it.
What happens if you accidentally click it and the cyanide gets injected into your leg?
