Hey...I sometimes feel the same way about people coming over...I have a house that I own and am pretty happy to show it off...but, to have a visitor for longer than an hour or two stresses me out...and I don't know why. I am not married and spend a fair amount of time alone (boyfriend and I don't live together) and think that I'm just used to my own company. I've gotten better at "small talk" over the years and can pretty much fake it at this point, but it's still something that makes me sensitive from time to time...but, the more you do it, the easier it gets....
