I got you friend :)
Answer: One example of direct characterization in the short story No Dogs Bark by Juan Ruflio is provided in the following quote:
"Though his legs were bowed by the weight, he did not sit down fully because he knew that afterwards he would not be able to lift his son’s body."
This quote is pulled from the beginning of the story and tells the reader that, even though Ignacio's father is tired and weak, he does not give up and he does not let his son go because he is determined to keep going and refuses to give up. This can tell readers that the protagonist has a firm, determined spirit.
