Insensitive

So many of us can be so cruel and insensitive about the simplest things.
I found myself being myself yesterday when I spoke with one of my sisters and forgot just how different we are from each other. This is quite disturbing but my sister has my mothers greeting from her cell phone on hers. She kept my mothers cell phone and didn't get rid of her greeting. When I call if my sister does not answer right away I hang up. Yesterday I called her and she didn't answer and right as I was hanging up I heard her answer but it was too late. I called her back and she made a comment about me not being ready to hear my mother's voice "yet". I don't want to hear it!
