So, I'm usually on the city bus, bussing to work, school, a gym, whatever and occasionally a cute girl will sit next to me. There's plenty of space in the two seater seats, just enough for an average person to sit in each one, however most of the time when a girl sits next to me, our arms are fully against on another, or the side of our thighs are touching, or both and the girls don't move. I don't move because I like the contact. Could this be incentive to just say something? Approach has always been difficult for me, but is this a sign that, for some odd reason, they don't mind me being that close to them? They do have an option to move. For example, a few times the bus would be slightly full, a girl would sit next to me, it'd empty at the next stop with plenty of empty seats but she wouldn't bother moving. I know that you should approach anybody you find cute, but is this tiny, tiny action basically a 100% "talk to her" situation?
