Notice how the word "publisher" is not mentioned.
Editor would be the more glaringly omitted phrase.
I dunno how it is nowadays, but your agent typically is the one who handles the financials/PR side of things, not the actual business of writing.
I'm also kind of amused that it took him, what, a week and a half to churn through all the rewrites? I'm pretty sure Patty is trying to stealth humblebrag but, uh, that's not really a laudable thing given we have a minute-by-minute tracker of Patty's actions thanks to Twitter.
For some extry context here are some relevent xeets
Most people would cite something like 'the birth of my child', 'my first dance as a newlywed', 'completing my love quest', 'publishing my first book', 'graduating head of my class', 'grinding my first child into pepperoni', etc.
You know, actual, definitive moments and memories in someone's life.
For Patty, it's clapping like a (fat, retarded) seal (with bitch tits) at some capeshit garbage no one is going to care about in 5 years.
What an utterly banal existence.
