I'm stubborn and I know it

This morning, Seth, Jonathan, Thomas and I (Jane Anne) talked about the time change. Jonathan and Seth had been up for a while. I was still sipping coffee trying to wake up and Thomas had just come downstairs. (David is sick and was still sleeping. Elsie was also still asleep.)

We began discussing who in the family is a "morning person" or a "night person."

It is clear-
Seth is a morning person.
Jane Anne is a night person.
Jonathan is a night person.
David is a morning person.
It is too early to tell about Elsie.

Thomas gets in bed and falls asleep fast and hard. Waking up can be a very slow process.

This morning Thomas was unusually chatty. Seth mentioned that he falls asleep quickly and surmised, "Maybe, Thomas is a morning person."

Jane Anne: "You carry him downstairs sometimes because it is so hard to get him to wake up. And, he sometimes he doesn't wake up when you bring him downstairs."

Thomas: "I don't think I am a morning person or a night person. I am just a person.
I am a stubborn person."
