For some odd reason, I check out the houses for sale on SF Gate. They choose two a week to entice people into the buying market. Of course, most are only affordable by a few. Today's offering is $3.95 million. It has six bathrooms, two of them for the master suite. It seems to me that if you sleep with someone, you would want to share a bathroom with them, but it seems that's not to everyone's taste.
In At Home, we also see incredible excess as one person may require a mansion and an army of servants to serve. One Lord didn't know that you had to put toothpaste on the toothbrush because his servant had always done it for him. Can you imagine that lack of disconnect with the world, thinking your toothbrush came with paste on it and then it was used up and then it magically reappeared? Perhaps that explains the deficit.
I suppose each of us thinks and feels "our home" is best. Mine is the perfect habitat for me and those I love.
