There's a Man in the Habit of Hitting Me on the Head with an Umbrella summary

When I first read this story I did not fully understand how one person could eventually become accustomed to being hit in the head with an umbrella. This story has an unique spin to it with an almost humorous response to the man hitting someone with an umbrella. It is also interesting how this story never tells you anything specific except for the man hitting someone in the head with an umbrella. I would recommend to read this it is a really interesting book with many different ways to view it. And if any of you can find the hidden riddle in the story just post it in the comment section.
