Milo's getting worse and worse about going to bed. At least he has the decency to be adorable in his pig-headedness:

• Milo: Something keep waking me up, Papa.
• Dean: What's that something, Milo? What keeps waking you up?
• Milo: It's a mouse. A mouse keep waking me up.
• Dean: A mouse? Really?
• Milo: Maybe a lion.
• Dean: A lion? In your room?
• Milo: Could be an owl, Papa.
• Dean: Milo, you haven't even been asleep to be woken up.
• Milo: It was a hippopotamus.
• Dean: Milo, cut it out!
• Milo: Papa, something wake me up. Maybe a beaver.
• Dean: (Starts giggling in the middle of a shhhhh)
• Milo: I do a trick, Papa. That was funny joke.
• Dean: It sure was. Now please, for the love of God, be still and try to sleep!

Felix has imaginary friends named Steven and Leia. They are twins; they were born on the same day as Felix; they like doing the same things he does. When you ask him about them, the details vary: sometimes he says they live under our house, sometimes he says they merge inside his body when other people show up because they are shy (= they are the same size he is), sometimes he says they live inside his body and are tiny, sometimes he says they are invisible to everyone but him.

When Felix plays alone in his room, he is really playing with Steven and Leia. Every morning, Felix likes to have some "lonely time" in his room before breakfast. He refuses to let Milo in his room. Since the rest of the time Felix is so good about playing with Milo, we allow Felix to shut out Milo until breakfast.
