I like to meet people on trains, but not planes. Planes are places where I don't like to talk much, except before boarding, because lots of strangers always ask me to watch their stuff, like their purses and carry-ons that are not supposed to go out of their line of sight. This makes me think I have a "warm" demeanor. Is warm the right adjective there? I also once met a really nice dude at an airport bar, but I can't remember his name. He liked my iPod.
