I'm deeply introverted, but I love the energy and bustle of people, and especially love the brownian motion of ideas and cultures colliding in big cities.
I associate nature with deep loneliness because there are so few people out there, and those who are out there don't really talk to each other. I've been camping, been on hikes, etc. with and without friends, but it's really not my thing. I like going fishing with friends, but forests are not my thing. As a kid I watched a movie about cabin life in Oregon and it left an indelible mark on me: I told myself I never want to live that life. It's so isolating.
I love being around people, even if I don't talk to them. I could sit in a cafe by myself and feel full just feeding of the energy of the overheard conversations and the relationships of people around me.
But as a Chicagoan, I do love talking to people. I love the inconsequential interactions like asking the receptionist how her day was, or the person in line about the weather.
