Both of these stories have a sense of realistic fantasy in them. They are obviously fiction but they aren't so far fetched as other fiction stories, these have a sort of realistic theme. Both of these show many things that would and do actually happen in real life. For example, in 'theres a man in the habit of hitting me on the head with an umbrella' he exclaims as the man is tapping him with the umbrella people laugh and kids make fun of him. This would happen in real life if someone was constantly being tapped on the head with an umbrella repeatedly. This is an example of the MANY realistic items in the story but the main item like the man tapping him with the umbrella, is fiction.
I hope this helped. Have a great day!
