> I guess I have enough solitary activities that I regularly partake in that I never gave thought to those that might need to actively seek out such activities.

I actually have to remind myself to partake in activities that involve other people (unless I'm currently working for a client on site). The bigger issue is true aloneness without that pesky internet. It's a powerful addiction.

Honestly, I feel more alone when I'm in the gym actively boxing with people than I do sitting at home where I can't help but check my messages ever couple of minutes.
