This Is Not The Letter Either

Here is a email interaction I had with W yesterday and today. Her anger at me was puzzling, as our last previous interaction had ended without anger.

W,
You seemed tense and angry when I talked to you on the phone tonight to bring up the subject of debt repayment.
I wish you could figure out some way to treat me with at least some baseline level of common courtesy and dignity that even strangers have for each other.
E

Her response today:

E,
I'm sorry I was rude. I have no caller ID on my home phone so have no way of knowing who is calling and really didn't want to talk to you right then. Please only call my cell phone from now on and leave me a message if I don't answer. That way if I answer it means I'm in a space to talk to you and if I don't it means I will get back to you when I am in a space to talk to you, which means I will have the ability to speak to you in a much less offensive manner than I did tonight.
W
