The letter was written – typewritten – on pale-blue notepaper. It had a handled, unfresh look, as if it had been taken out of its envelope and read several times before: (Franny.1.3)
Lane obviously cares for Franny, as we see by the number of times that he's read and re-read her letter, yet he doesn't reveal this to her.

All my love,
Franny lacks all the reticence that characterizes Lane.

"I've just felt so destructive all week. It's awful, I'm horrible."
Franny has just delivered a dagger of a confession to Lane – that it took effort on her part to sound loving in her letter – and all he does is focus on something material.
