This link has been put about on Facebook, but I know some of my readers have not, so I will repost it here.
Roger Ebert is best known as a movie critic, but ever since cancer and the attempted treatment of it changed his life, he has emerged as a preeminent modern essayist (in the form of his blog).
This post about loneliness struck a chord for some of my friends, and it does for me as well. One thing he did not bring up, but a commenter later on does: some of the loneliest times I have ever experienced were in the presence of another person. I would state "most of the..." but I have a crappy memory and I'll give myself and others the benefit of the doubt. For me, loneliness is about connection and sharing - or lack thereof. Most of it can be avoided by exerting oneself, and the remainder must be endured.
It sounds like it might be a sad post, but it's not really. Just thought provoking.
