I have been trying lately to articulate why I feel so strongly about living in a house that is cleaned regularly and on which some degree of order is imposed. Joanna of The Modernity Ward hits the nail on the head by drawing a distinction between housekeeping and homemaking. More on this later; but I have come to realize that the act of homemaking, in my family, was an expression of ultimate love. To care about those you live with is to want to make a space welcoming and generous for them.
I've got to sit down sometime and think about this more, but now it's time to watch Buffy with my husband.
ETA: Here's some more on homemaking as an act of profound love from Marta of My Goodly Heritage.
