Unfortunately, you asked two separate questions, so I had to edit out the second. Please feel free to re-post it as a second question. Listing page numbers and lines will not be very helpful, I fear, because I have no way of knowing in what anthology you are reading this story.
Raymond is an essential character in Toni Cade Bambara's "Raymond's Run. (We know that, of course, because this story is called "Raymond's Run" though it is actually about his sister's running, in terms of plot.) Raymond is the mentally challenged brother of Miss Hazel Elizabeth Deborah Parker. It would be pretty difficult to find several lines of dialogue for him since he never speaks, so perhaps that is one excellent example of how Raymond views the world. He does not join it: he simply looks and listens. Even when one of the girls in Hazel's class try to goad him into conversation, Raymond does not speak. His sister does the talking for him.
A second example of how Raymond views the world is seen in his climbing the fence after Hazel ran (and won) the race. Again he does not speak, but Hazel hears him, nevertheless.
Then I hear Raymond yanking at the fence to call me and I wave to shush him, but he keeps rattling the fence like a gorilla in a cage like in them gorilla movies.
This image, of a young man being trapped in a cage, is apt for Raymond. His limitations have him trapped, and he must surely feel as if he is caged in a world with which he has so little in common. He is generally happy, though, so perhaps he sees the world more like it is--the "cage" is really just a fence (barrier), not a cage.
The good news in this story is that Hazel not only protects him, and certainly has the ability to do it effectively, but she also recognizes that he has the potential to break out of that cage (or out from behind the fence) as a runner and is willing to teach him. Until that happens, though, Raymond lives in a silent, rather caged (shut-off) world.
