When you KNOW something to be true and someone else doesn't
   listen to you... it's very very hard to handle. I find myself
   explaining something 10 different ways, 20 different ways,
   whatever it takes and TRY not to lose their ears.

   Once someone grows deaf to me, there's not much i can do. And
   it's hard. While I don't know the specifics of your situation, I
   can relate in my own fashion.
