When Gabe starts talking, he doesn't stop. He talks all the time, continuously, he always has something to say, even in his sleep!

Gabe talks and talks and talks, non-stop. He sings songs, recites tongue twisters and answers all the teacher's questions. He speaks when he should and he speaks when he shouldn't. 

And so, people around him start wishing he would occasionally stop. And they wish for it so much that one morning Gabe wakes up…and his voice is gone!! What's happened to Gabe?
