What does Cherry mean when she says “Bob wasn't just anyone"? What did she manage to see in Bob that others did not?

Cherry was not so silly as to think that Bob was perfect;
she abhorred the violence between the Socs and greasers, and she truly liked Ponyboy and
Johnny, although she felt helpless to fight the elite social structure in which she was
firmly entrenched.  However, she also seemed to understand something of human nature,
i.e. she was more perceptive than perhaps the average teenager.  She sensed right away
that Johnny has somehow been hurt badly either emotionally or physically (when in fact
it was both) and she understood that Bob's problems related to his upbringing or lack
thereof.  No one had ever told Bob "no" nor had anyone ever held him accountable for any
social norms or boundaries, certainly not his parents, and in that sense, Bob was abused
as well.  He wasn't beaten like Johnny, and his outward appearance was such that
everyone assumed his life was great, but anyone who's worked with teenagers for any
period of time at all knows that they crave boundaries, even as they are fighting them,
and Bob never had any.
