And in the category of "Performance by an Asshole" the nomination goes to:

My ex husband, for the following exchange

Ex: calling about travel arrangements for Youngest  Child today
Lass: information about road conditions where we life
Ex: tentative arrangement
Lass: agreed, call me when you're ready to leave the city
Ex: "I'm just wondering about our financial obligations to Eldest Child. I've just been informed she expects me to pay for her replacement passport"
Lass: I don't know what you mean, and yes, she is broke, and her passport needs to be rush replaced. I have no plans to cut her off, she`s only 19.
Ex: "But I'm wondering about our financial arrangement about her. Can I expect to see this money back"
Lass: I still don't know what you're talking about; if you expect her to pay you back, you should talk to her.
Ex: "I think we need to talk about the financial arrangement. I gave her $100 last week"
Lass: And I gave her $140 two days ago. She`s broke.
Ex: I`m wondering if I can expect you to pay me back for money I loan her....

Lass: *head explodes* If you aren`t willing to give her money, then you need to tell her that. And I will continue to financially support her and  we will deal with it. I don`t really understand what you`re asking me.

Ex: We just need to have a conversation about this. I don`t think I`m being unreasonable.
Lass: If you are expecting me to  raise Youngest Child on my own, with almost no support, and think that I have enough money floating around to help Eldest Child, and also pay you back for any money you loan her; that is not happening. I don`t have that kind of money.
Ex: I don`t know what you`re getting so upset about. I`m not being unreasonable. And you`re on speaker phone  in the car. 
Lass: *head exploding again*
Ex: It`s not like we ever shared finances equally in supporting Eldest Child (ed note: not a single fucking penny in child support because he opted to suddenly play the `just a stepfather` option) --- so I don`t see why we`d start now. We just need to talk about it.
Lass: Goodbye.
