In my experience and anecdotal research, there are 2 types of airplane travelers. There is me. I'm quiet, polite, and pretty much keep to myself. I'll pick things up if you drop something, pass you your bag if needed, but generally mind my own business. Then there is the talker. They don't keep to themselves or mind their own business. They tell you all about the film you're watching, where they've traveled from (and to), what they do and all about their family and friends. I am definitely not one of those travelers.
