Following a definition of a hermit as a person who has withdrawn from society and lives a solitary existence; a recluse...I would say no, I am not a hermit because I have a job and interact with society pretty intensely through work.
However, the older I get the more isolating I am becoming in my non-work life. I don't necessarily seek out solitude...but social options do become more limited as you grow older and peers get married and have families. I also have a diminishing tolerance for "bullshit", be that defined as people that take and never give back, or people who use others, or people who are not what they seem, or people who are generally negative and waste my time and energy. I think most of the time I would rather stay at home alone than spend time with people I really don't like being around.
On the other hand, I do have bouts of loneliness...which is cool because it is an indication to me that I'm not totally an anti-social hermit. In a perfect world I would have a great friend who lives two doors down who walks in my house at whim and we grab a pizza or watch a movie. That how the sit-coms work...but that situation does not exist for me. :wink:
