Mr. Gordon seems like a good guy, at heart, even if he is a curmudgeon. We get the sense that he is very nostalgic for his son's childhood, which is bittersweet.
You have a little trouble with pronouns in this part, when it switches from describing Mr. Gordon to describing a woman:
After an hour there is a knock at her door, once again snatching her dream of beauty, for 50 years do not pass in vain.
She opens it and sees a 14-year-old brat with his cap backwards, his shoes worn out and his clothes covered in dirt.
If this refers to Mr. Gordon, it should be "his door," "his dream of beauty" and "He opens it."
Keep writing!
hello @jayna thanks for the observacion, my mother tongue is not English and I often make grammatical mistakes (horrors), so I try to improve daily, again thanks for the comment.
