What does Cherry mean when she says Bob wasn't just anyone?
As was mentioned in the previous post, Cherry is explaining to Ponyboy her relationship and perspective on Bob Sheldon. To Cherry, Bob was not just a violent Soc who enjoyed fighting Greasers and getting drunk. Cherry understood that Bob had two different sides to his personality and tells Ponyboy that Bob was actually a sweet, friendly individual. She goes on to tell Ponyboy that she loved Bob, and he had unique charisma that made other people follow him. The Socs looked up to Bob and viewed him as a leader. Ponyboy is initially upset that Cherry feels this way about Bob because he is more concerned with Johnny's well-being. Cherry explains to Ponyboy that she also recognized Bob's negative characteristics but could not bring herself to see the person who murdered her boyfriend. Before Ponyboy leaves, he expresses his friendship to Cherry by asking her if she could see the sunset real good on the West Side.
What Cherry means here is that she was really in love with Bob. She is saying that he wasn't just any boy -- he was someone special.
This comes about because Pony asks her if she's going to go visit Johnny in the hospital. She says she can't because he killed Bob. She knows that Bob did bad things. She knows that he was the one who beat Johnny so badly. But she blames that on alcohol and wonders why people sell to teens.
When he wasn't drunk, she says, he was really nice -- better than the other people in her crowd.
So what she's saying is he was special and that's why she loved him.
Cherry states she knows she is too young to be in love but that Bob was someone special - not ordinary. She felt he had great qualities except when he was drinking. While she knows Bob beat Johnny literally to death, she did not want to look at the person that killed Bob.
Cherry was very much a realist and considered more facets of a person than most people her age would. She was able to see what Bob was and would eventually become had he not been killed.
