I want that on the record, because the story is easy to tell as a revenge and it was not a revenge.

It was a correction.

I had simply stopped being the answer to a math problem the family had been refusing to do, and now, for the first time, they were going to have to do the math themselves, in public, together, with the check already on the table.

It was not a trap I had set.

I want that understood.

I had simply stopped stepping into the place where the family had always, without a word, expected me to stand, and the absence of me from that place was the whole of what happened; everything else they did to themselves.
