Teddy's eyes flicked between Caleb's mouth and his hands. Since his signing was a little clumsy, it actually helped Teddy some that the other teenager was mouthing what he was saying. He nodded to indicate that he understood what was being said to him and he just shifted on the bed, clearly excited at what was happening.
He pushed his hand through his hair and then signed Good! I did some studying and heard from my mom that my brother is going to be coming to the school too. He paused, biting his lower lip and looking a little sheepish as he had sort of sped through those signs.
He repeated the phrase again, waiting to see if Caleb needed any clarification. So far the guy seemed to be pretty okay, better than Teddy was expecting considering. And that was good, that was really good!
He rubbed at his ear and pulled the pad a little closer to himself just in case. [Using letters is O K, BTW.] he added with a little grin.
