I enjoyed this article. I've lived with other people my whole life and it seems most young people I know live as roommates even into their 30's (if they are not cohabitating with an S.O.) I have had "Days of Chad" though and wonder what it would be like to love totally alone. I personally would just feel less social and more bored.
I've lived alone for almost 4 years now. I don't crave companionship and am perfectly fine with my own thoughts (introvert). Boredom only sets in if you have nothing interesting to do. My apartment is sparse; no television, empty walls, no game console (asides from 3DS/iPad), no way to entertain people who come over outside of whatever I can display on the computer. How the hell is that enjoyable? You find the things…
P.S. I've also grown up with siblings, lived with other people - I don't like that, I really like privacy, I guess :-)...
