"That's How He ..."

Vincent and Aubrey were discussing Silas's toy use yesterday. Aubrey asked why Silas was chewing on it, and Vince was trying to explain it to her, but it went something like this: "He just likes to chew on some things, Aubrey. Because that's just how he..." He seemed to be at a loss for the right explanation, so I interjected, "Vince, I think the term you're looking for is 'rolls. That's just how he rolls.'"
