"Oh, Matthew wasn't programmed to talk," Flint said, "he's a mute. Instead, he has emoticons appear above his head when he needs to talk. Matthew and I have linked minds, so I do most of the talking."<br/>Matthew nodded and smiled as a yellow smiley face appeared above his head. Flint turned to Matthew.<br/>"And speaking of food, do you have any? Like, any leftover bread or any nuts or anything?"<br/>Matthew searched through his satchel, and a grey frowning emoticon appeared above his head.<br/>"I'll take that as a no," Flint said.
