This news showed that the narrator's uncle and grandmother died and he couldn't even say goodbye, as he was too faraway.

I had an English teacher like this once. She was notorious for giving students grades off the rubric. (Such as a grade below 30 even though the lowest grade on the rubric was 60). I recommend talking to your principal, parent or another teacher regarding this.
