Jason,
Ten years is a long time and a great milestone. Have a great time on your anniversary and may you celebrate your 50th together too
I agree with Eddie when it comes to insurance companies except for the anger part. As someone with a redhead's temper, I've learned the hard way what my mother told me all my life - you catch more flies with honey than with vinegar. I think you might have a battle with a change in device. But then again, you never know.
Regardless, good luck with your surgery and please keep us posted.
My best to you, Dale
