You're absolutely right and handled the whole thing great. She is pushy and nervy.

It's too bad you couldn't just enjoy a little book club without the stress of feeling used.

I've had to deal with my share of Karens myself. And when you call them on being rude, they do act offended, and they rally others against you. So you have to deal with them in a passive/aggressive way or just get away from them.

For example, you'd make up some fake excuse for not holding the next meeting at your house, forcing someone else to step up or the book club is done.
