"Can we go outside and play?"
"Yes. Go."
"Can we ride our bikes?"
"Yes. Get them."
"Can we go inside someone's house?"
"No."
"Can they come in? We're just going to watch t.v."
"Yes. Just for 20 minutes. We're about to eat."

Suddenly, there is a little girl with a snow cone (that my son apparently made for her) on the end of my bed, taking off her rain galoshes while watching a cartoon on my television and simultaneously telling me something about her grandmother. On my bed. In my room. Taking her shoes off.

"Does their mother know they're over here?"
"Yes. She's going to come get them at 6:30."

It is now 5. So much for 20 minutes.
