Caring was something Teto stopped long ago.
They put one person's life above another's. Everything was stacked in a social pyramid, with the weakest at the bottom.
Maybe Teto wasn't the most popular. Maybe she wasn't the most athletic. Maybe she wasn't the most important.
But she definitely wasn't the weakest.
The weak just let things happen and just take it. They never do something about it, but they think they can.
Whereas Teto watches it unfold, but she knows she can't do anything about it.
Those were two completely different things.
She definitely wasn't weak... Right?
Note that the last line was Teto's first question.
A bit of development in this chapter... Teto is becoming a bit more insecure in what she's saying. She just said that she didn't care, so why is she worrying about her metaphorical social pyramid?
