It happened a week ago or so...I was on my way to have some work out session with friends. I got on the Suburban Railway at the terminal. At the very moment I took a seat a girl dropped in the car and asked if she can sit there too. There were still a lot of empty four chair compartments, so I took not following the Pauli principle as an AI. We sat down oppositely. Both of us had our earphones on so we didn't started to talk and anyways an other guy (could had been our father) sat there as well. The car had been filled up quickly, and the train started off. (In these kind of sutiations I always turn down the music and free one ear secretly to be able to catch up with the happenings...so did I now) She got a phonecall from a stranger. It was an agent trying to get her meeting him later speeking about financial opportunities. I didn't need a better cue...when she hung up I started a conversation about how annoying the agents are...easy win :) the other older guy followed up but remained in silent (he apparently knew what I was up ot to) We discussed where we were going...etc. Then we'd arrived to her stop, she got off, but I didn't. There was no close for the situation (except I'd heared her name when she answered the call...I can look for her on Facebook) So she got off, and then the guy said I had to always get off in this case, no matter what. And I know he was right I'd known it at the moment the doors had been closed. My advice for you all: always get off!

Edited on DrZippit's request: always get off the train :D
