Imagine going to your favorite coffee shop by yourself, like the one I'm in right now, The Tahoe House (www.tahoe-house.com) in Tahoe City, CA.  ( I highly recommend it for the food and the atmosphere.)  You know what it's like when you get there at that perfect time when it's really quiet and you can get your favorite table?  You coffee house junkies know what I mean.  You sit down with your favorite beverage and pull out your book or computer and settle in for who knows how long.
