I think it has to do with personality types. I teach school but prefer to be at home when I can. I love to entertain...we always have a houseful at holiday time. But, an example is tonite...I had no desire to go to a Super Bowl party where I would have to mingle and make small talk. I much prefer to be here at home watching the game and playing on my laptop. And I prefer daytrips to overnite trips...I don't have the hassle of boarding the dog, etc. Yes, I am a homebody as well and I see nothing wrong with it.
