I'm starting this for my daughter eternity she was born deaf and Loves to play with other children . So when she sees other kids play in she runs over to them. Well in our neighborhood that is not a good thing. We live on a one way street people fly down and go the wrong way. I have asked for a sign to b put up to warn people that eternity is deaf or something that will help . So now I'm taking it into my own hands please help us. Thank you.
