My home has 3 1/2 bathrooms. I eat meals at my kitchen peninsula, for convenience. I'm so organized that if guests are coming to dine, we either eat buffet to my large covered porch or in my spacious living room in front of the fire place. I did enjoy a fourteen people sit-down Thanksgiving meal a few years ago in my dining room.
When I was a boy, our home had an 'outhouse'. I helped dig the pit over which it sat in two locations we used over several years. I built my current home and installed two septic systems ... have two laundries, one up and one downstairs.
