Every time I think about the Letter, and it keeps coming to mind, I feel like I hate Hannah a little more. I think she learned to do a good job at feigning empathy, or at least a good job at getting by at feigning empathy when she was surrounded by family and friends. She had learned their cues, what you are supposed to say, what is important to echo back in response, what they will put up with. What to hide. And now she is in a completely different environment, not just new people but new people who aren't cut from the same cloth she has been learning to wear all these years. She doesn't have the old people to run back to for validation about every little thing the new people do that throws her either, she has no outlet that might help her keep her mouth shut around the new people. So we see the raeal Hannah, without the props she's been clumsily leaning on for so long. The self absorption is staggering, it's at mental health issue levels IMO.
