Bare foot and pregnant

I never wondered before about the phrase "bare foot and pregnant." I suppose I thought it had to do with being a house wife and not needing shoes on account of nowhere to go. Now I know the truth. I have places to go, but most of the time my shoes don't go with me. For the past 2 months I have increasingly eshewed my "real" shoes in favor of house shoes. For the past few weeks it has ben an exclusive relationship; shopping, work, special events- all have been attended by my house shoes.
