I liked that you told more than one story, that was dope.
I think the teacher's story could have been elaborated on more.
You seem to have the technical aspects down, but try experimenting with different flows and formats,gives you a challenge when you write.
I think there should have been an outro...piece with an intro should have one.
just looks like it died after the beggar's story, know what I mean?
maybe try leaving the reader with a moral
