Answer:
"He looked up in time as we crossed toward him and said, 'Happy birthday little sister.' I smiled and said, 'Hey Russell.'"
Step-by-step explanation:
Rita Williams Garcia's non- fictional narrative "About Russell" is a memoir of the author about her younger years and especially about her older brother Russel.
In the narration, Garcia recalls how her family had been some couple decades back. Her brother Russell used to be a bright boy with lots of ideas stemming about anything. but as time passes, he developed a sort of forgetfulness that the family refuses to accept as a "mental illness". But the author was sure of her brother's mental issue and had always tried to point it out in the family. The passage
"He looked up in time as we crossed toward him and said, 'Happy birthday little sister.' I smiled and said, 'Hey Russell.'"
is from the last lines of the story. This part shows that even after so many years and his declining personality and mentality, his mental illness had not severed family ties. This is true for they happily greeted each other whenever they meet or encounter each other, and the author being a successful women while her brother is rummaging in other people's garbage bins. This difference in livelihood does not affect any tie that binds them.
