American Realism-Short Story Journaling

For my assignment I chose Mark Twains short stories and they were fun to read. Twain writes stories that almost seems real but it is fiction after all.
Twains stories are very entertaining and you never know what will happen next. The story of "The good little boy" and "The bad little boy" are very ironic in a sense. The good little boy would do nothing but nice things and nothing but bad things would happen to him. On the other hand the bad little boy would get rewarded for his naughty deeds.
When I was reading these two stories I thought that maybe Twain writes to teach a lesson, sort of like a fable. Like in "The jumping frog of calavares", Twain could have been teaching a lesson about karma, or to be careful who you mess with because no matter how good you are at something, theres always gonna be someone better.
