Plus you probably have to fight traffic and drive for 30 minutes just to stop at a grocery store, and it probably ends up being a 2-3 hour ordeal.
See, I live in the biggest city in Montana, and we have about 100,000 people spread out across about 100 square miles. It takes me 12 minutes to get to work when I hit most of the lights during traffic. I can get there in 5-6 minutes at night. I have 3 grocery stores within 3 minutes of me, and only WalMart is busy enough to make it frustrating. And I work in an office with the same 14 other people with virtually no interaction with anyone outside that office.
I still understand your situation, I am somewhat of an introvert and I don't need to be around a lot of people to enjoy myself. Plus my house is my sanctuary, I ENJOY being here, and I spend a lot of time making it exactly how I want to live. When I was married I enjoyed nothing more than going home and being there. I had no need to go out or do anything. I hate shopping so I always sent the wife for that stuff, and she enjoyed it (too much, unfortunately). The last 4 years has been different, I have had to get out and socialize more unless I wanted to spend all that free time alone, and I find I like it now and then. I love having people over now and I have a great deck, firepit, and game room that is all one big entertaining space and I regularly get 6-12 people over to enjoy it with me. Despite having a steady girlfriend most of that 4 years, I still like getting out of the house.
Now today, I would like to just stay home and be alone.. It is cold and raining, I had to spend the last 4 hours clothes shopping for my two teenage daughters (and no I didn't go to the gap, lol), and now even though I am thoroughly finished with the human race for a while, I still have to go to a wedding for a friend shortly. Otherwise I would kick off my shoes and just call it a day. Or I would be in my shop starting the construction of my next cabinet, but either way alone and not out in public dealing with people.
