It's because . . .

The reasons our six-year-old granddaughter might have a permanent hearing loss:

• Mom and dad are too busy pissing at one another to really make the kids proper priority.
• Dad neglected to get her antibiotic prescription filled and to tell mom about it. 
• Mom is too wrapped up in her ADD to be willing to get out of bed to take care of her kids as she needs to, so waited 4 additional days to get her back to the doctor from when she knew she had to go.

I'm a wee bit angry, and am venting here because I just might assault someone if I don't. 

These precious kids are utterly dependent on the two of you gathering your defecation. If you can't do it on your own - and you clearly can't - then grow up and get the help your children need for you to get. They may be resilient, but they're also fragile, and you're breaking them.
