At Arms with Morpheus

I read "At Arms with Morpheus" by O'Henry today.
I liked the humor which the story includes.
The humor is "funniness of a very sincere man".
Tom, who accidently hasvtaken morfine, is supposed to be funny and foolish
because he is too much honest. He believe all nonsense talk of his friend and try to warn himself.
But I think such a man is pretty cool even though he is scrupulously honest.

Here is one part from the story that describes Tom's character.

"He was good nature itself, and a gallant gentlman, fine and true and clean as sunlight.
He came from somewhere down South, where they still have ideals and a code. New York had charmed, but had not spoiled, him."

People might say this kind of person is tacky or out-of-date.
But I believe O'Henry liked a man such as Tom Hopkins and wanted more men respect Tom
hopeing not to lose faithful men in the US.
