Silence with Granger was different, he’d realized from their study session a few days prior, and it was all the more obvious now.  With most people silence held expectation or a need, with her it was...restful.  She had no expectation of him, or anything she wanted out of him.  She just let him exist.  Even with his own mother he was expected to hold himself a certain way in order to convey a message in the silence.
