Incomplete question. However, I inferred you want to know the characters from the text.
Step-by-step explanation:
Main characters: Jerry, Jerry's Mother.
From the story, we could notice that Jerry and his mother (Jerry's mother) seem to be the main channel through which the reader can experience the story. In other words, what they experience is also what the reader also experiences.
For example, we are told, "due to him being all she had in her life since she was a widow and Jerry was an only child." So we could notice from the quoted line that it gives the reader insight into the life experiences of the main characters.
