Well, it's not really a secret if you have ever visited my house on any day of the week. . . or weekend.
My 6 laundry baskets (some are buckets) are perpetually filled, even overflowing, with clothes. Most of the time they are clean, but once they make it upstairs, they take refuge in the living room and any member of the family can be found rummaging through them in the dark morning hours looking for underwear and socks.
Travel a little ways into the hallway, and you will find 3 rooms. Each has a dirty laundry basket which is usually filled more times than empty. Residing close by in each of these rooms, you are also likely to find a basket of clean, folded laundry that is begging to be put away.
Travel down the stairs to the basement and chances are you will hear the washer running, usually more so than the dryer because the load I did 3 days ago that has now sat in the washer too long needs to be washed again.
On a good day, you might find me in the middle of my living room, surrounded by piles of clean, folded laundry, awaiting to take refuge in a basket, holding out hope that the laundry fairy will come and put them in their proper places.

My secret is out.
By the way, if you see that laundry fairy, could you remind her of my address? I think she has forgotten where I live.
