who's to say were all phonies?

I think alot of the reason Holden labels people as phonies is because he doesn't to try and connect with them, he doesn't want to even try and put himself out there for the world, so giving the name phonies to people give him a cover.
His phonies radar goes off big time with Sally after spending only half hour with her, at first he was totally head over heels and just wanted to move away only with her, his lust fell short soon after he talk with a guy she knew. Holden once again didnt want to keep trying after he got annoyed and just left it at she's too much of a phonie and that's when his bad side got the best of him. Also I've notice Holden always leaves people on bad notes, with Stradlater, Sally,Old school mates, His old Teachers ect, they all have this bad idea about Holden now.
But as long as Holden thinks everyone else are phonies, i think he is just as much a phonie too.

say, mean, better?!

""Did you ever get fed up?" I said. " I mean did you ever get scared that everything was going to go lousy unless you did something? I mean do you like school, and all that stuff?""

I think in this paragraph Holden is really trying to find another way to relate to this girl, he's looking beyond the outside figures and surfaced comments and trying to look deep down and find if there is anyone hope that anyone else feels like he does. Almost trying to show that he cant be that much different then everyone else if other people are feeling how he does. I believe this is very important for Holden because unlike other people he has had sit down conversations with, he is really trying to look for a real connection, a real like person who's not all phonie.
