How does this house work?

I was at the computer at 6 o'clock this morning when May appeared at my side and said, "I need someone to explain to me how the house works." I walked her back to the bed and asked her to explain what she meant, and then there was this:

"What do you mean, how the house works?"

"Well, there are all these people, coming and going. And I just don't know, I don't know how it works..."

"Okay, let's count the people. There's you and me and Adam. Adam's been with us since we bought this house. And then there's Ted, who's been living here since Thanksgiving. That's four people. Ted comes and goes. The rest of us don't."

"Where did this house come from? How did we get here?"

"This is our house. We own it. You like it, you like this house."

"I love this house."

"Yes you do. You tell me that all the time. You love this house."

"But, we own it? It's ours?"

"Yes, we own it."

"When did we get this house?"

"We moved in here in December, 2005 -- so, four-and-a-half years ago."

"And we own it?"

"Yes, we own it."

"Okay, okay."
