Honey pick up the phone
You can learn a lot from people just by listening how they, as recipients, respond to the questions posed by their friends on the phone. Yesterday I was on one of my journeys to the center of the universe, and the train was a perfect place to start my research. I was in a Linnaeus mood and decided to classify them into categories. One of the specimens was talking to his friend (I presume) and for twenty minutes he just kept asking questions but never answered a question himself. So I decided to put him into the shy-boring category. But then in the time lapse that the train hits a railroad switch, the moment when you bump into the creepy obese person sitting next to you even though you tried your hardest to avoid physical contact, that moment, I felt sorry for him and wondered if anyone had asked him how he was doing today.
Or maybe the guy was just related to Socrates and had inherited that dreadful quality of asking questions.
