Are they really paying attention?

(no pictures, it's amazing!) Today as I was driving to the library I was listening to the kids talk to each other. Holly was trying to say (I think it was) jet or something with a t at the end. She kept leaving the t sound off. Joshua kept correcting her, saying,"JE-T, T do you hear the Tah?" She tried again. He repeated himself. After the next time he said, "Look at my mouth, JE-tah." Holly finally got sick of him and said,"I'm talking to mommy." So he is listening to us while we're trying to improve his speech. Poor Holly is going to get three teachers instead of two.
