It was Corinna’s part in it.

Because it meant that the whole performance of family, the whole pretense that I’d married into something, had been exactly that: a performance, maintained precisely as long as I was useful and no longer.

My mother-in-law had sat at my table, worn the bags I bought her, accepted the trips I paid for, and the entire time she had been quietly shopping for the woman who would take my place once my husband had taken my money.

There is a particular cold clarity in learning something like that.
