Which of the following passages demonstrates Holden's desire to protect the vulnerable from experiencing the difficulties of adulthood?
“The thing is, most of the time when you're coming pretty close to doing it with a girl, a girl that isn't a prostitute or anything, I mean she keeps telling you to stop. The trouble with me is, I stop. Most guys don't. I can't help it. You never know whether they really want you to stop, or whether they're just scared as hell, or whether they're just telling you to stop so that if you do go through with it, the blame'll be on you, not them.”
“She was having a helluva time tightening her skate. She didn't have any gloves on or anything and her hands were all red and cold. I gave her a hand with it. Boy, I hadn't had a skate key in my hand for years. It didn't feel funny, though. You could put a skate key in my hand fifty years from now, in pitch dark, and I'd still know what it is. She thanked me and all when I had it tightened for her. She was a very nice, polite little kid. God, I love it when a kid's nice and polite when you tighten their skate for them or something. Most kids are.”
“I took my old hunting hat out of my pocket while I walked, and put it on. I knew I wouldn't meet anybody that knew me, and it was pretty damp out. I kept walking and walking, and I kept thinking about old Phoebe going to that museum on Saturdays the way I used to. I thought how she'd see the same stuff I used to see, and how she'd be different every time she saw it. It didn't exactly depress me to think about it, but it didn't make me feel gay as hell, either. Certain things they should stay the way they are.”
“I was half in love with her by the time we sat down. That's the thing about girls. Every time they do something pretty, even if they're not much to look at, or even if they're sort of stupid, you fall half in love with them, and then you never know where the hell you are. Girls. Jesus Christ. They can drive you crazy. They really can.”
“But while I was sitting down, I saw something that drove me crazy. Somebody'd written "Fuck you" on the wall. It drove me damn near crazy. I thought how Phoebe and all the other little kids would see it, and how they'd wonder what the hell it meant. And then finally some dirty kid would tell them all cockeyed, naturally what it meant, and how they'd all think about it and maybe even worry about it for a couple of days. I kept wanting to kill whoever'd written it.”
