What did I say?

So I got into an argument with my mother last weekend. Now she's moving to Delaware, I've only just learned (from my sister, with whom my mother is still speaking).

She was supposed to move here, to Oklahoma, from her temporary home in Indiana, once things were settled at her formerly permanent home in Philadelphia. Confused? That's okay. Because deep down inside, it's not your business. I just needed to express my befuddlement.

I couldn't tell you exactly what I said to set her off, but it had something to do with my "emotional insensitivity". This is a shortcoming I've always fully acknowledged, but ironically I've always felt it was derived from the way my mother raised me.

Now I'm confused.
