what are 4 characteristics of david's personality and how are they demonstrated ?

I can give you three:

-David is empathetic. He tries to help Sophie and cares about her even though she has an extra toe.

-David is open minded. He does not see "deviants" in the same way as his father.

- David feels burdened by the narrow ideology of the community. He can't even joke about having an extra hand.
