Answer:
This shows that Charlie is developing his perception of emotions, which is totally different from what he was able to do before.
Explanation:
The excerpt presented in the question above can be found in the book "Flowers to Algernon" where we know the character Charlie, who has a mental disability that does not allow him to have a good cognitive and rational capacity. However, Charlie undergoes surgery that lessens the mental disability he has, causing him to undergo gradual changes during the story.
In the excerpt shown in the question above, we can see one of these gradual changes. That's because Charlie was unable to interpret the emotions he had towards other people, but now he can understand that Alice Kinnian pleases him and that it provokes positive emotions for him.
