I much prefer my 'ME' time at home. I'm a homebody through and through. I work retail and love dealing with the public, but don't socialize much. I don't go out with many people other than my DH, DD and SIL.
My DH is a home body too. I'm thankful that for the most part we work different shifts so I get my 'ME' time. I"d go batty if I didn't have that.
I do agree there is a difference in being alone and being lonely. I think we are all comfortable with who we are and are perfectly normal being homebodies.
