Miles gave a sheepish smile, feeling a bit foolish for having reacted the way he did. In his defense, he know the psychological reasons for it, but there wasn't any need to go into that. No one would care anyways.
Miles was used to having random, and sometimes not-so-random, knowledge that no one seemed to care about. In most of his 31 years, he had just been a sponge, soaking up information easily. He'd start rambling to his siblings about the history of the television set, or something else electronic, and eventually they'd both just walk away laughing at him. It's not that they didn't care, per say, it was more that they couldn't stand there too long listening to him ramble about random, not so important, information when there were other things to do.
"Thank you," he offered. "I'm still not used to," he paused, trying to find the right word, "freedom. They didn't have me for long in the grand scheme of time, but the human mind can only take so much until it breaks." He may have said mind, but that was because he wasn't completely sure if he believed in the human soul and spirit. But one thing was certain for Miles, something in him did break while he was captive, and it didn't help that he had already been partially broken. Now, he had a chance to complete rebuild himself. But, one step at a time.
He took this conversation with someone other than Lou, and a man at that, as a good step forward.
