I have lived alone for about a quarter of my life, and I've realized that I like it. I would not say no to a relationship. but it's something I can live without.
In the past people used to accept hermits as spiritual figures (although the stereotype of the hermit as evil wizard or witch also exists) who possessed a special wisdom or skill. Nowadays, we're more likely to hear about "creepy loners" or "crazy cat ladies." Above a certain age, anyone who has never partnered, whether male or female, is considered suspect.
