This is more directed toward the single-single dudes. I would imagine being married or living with someone would make things a bit different.
For example, I live on my own without any roommates and I'm kinda of surprised by the lack of entertaining I do. Most of the time I prefer to meet with friends at a venue, bar, restaurant, or outdoors. I have a pretty big apartment, too, by New York City standards, at least.
How about you guys? Is your home/flat your fortress of solitude as well?
