Overall, quite good. A few technical quibbles could easily be solved by a good proofreader. That would catch stuff like using 'things go worst' instead of 'things go worse' there near the beginning.
Thematically, not the greatest fan of the son & bully both seeming to be so immature. I'm not going to post the age that they seem like, but I will say that I doubt either of them are graduating high-school this year. Its one thing if the son is innocent and naive -that just makes him seem more pathetic. But the bully, in my opinion, should have come across as a man compared to the son. Every mention of him being a boy, or small, or anything like that simply took me out of the story until I 'fixed it' with a mental edit.
