Maybe it is....whenever I travel in London no-one really engages, no one looks at anyone, they are all just wrapped up in their own stuff. Locally I waffle down to the village shop and everyone wants to pass a few words even if they are total strangers.
I love solitude. Only I don't feel alone at all. I love working from home! I'm sure folk would be healthier and get more done if they worked from home. I feel sure it will be more common in future times for certain jobs. Would you change your job to something you could do from your own sofa?
