I Miss My iPod

I recently contacted my estranged wife and asked her nicely to send me my iPod which she absconded with when she left me. It was not "our" iPod, for it was a birthday present to me from my father. Of course, she did use the iPod while we were together, but I don't think I'm out of line thinking that she should have left the iPod with me.
So I ask her via email to send it to me and she responds with one line, "Chill out about the iPod."
Besides the obvious, the fact that she uses the word "the" instead of "your" is very interesting. She obviously is under the impression that it is OUR iPod and not MY iPod.
I'd be angry if it wasn't so damn funny.
I miss my iPod.
