Happiness is often presented as being very dull but, he thought, lying awake, that is because dull people are sometimes very happy and intelligent people can and do go around making themselves and everyone else miserable. He had never found happiness dull. It always seemed more exciting than any other thing and capable of as great intensity as sorrow to those people who were capable of having it.
