He became more blandly garrulous [garrulous = excessive and trivial talk]
He declined the proffered hospitality
He dropped into an eloquent silence
He eludes analysis and baffles description
He glanced at her indulgently
He had the habit of self-engrossed silences
He harbored his misgivings in silence
He poured bitter and biting ridicule on his discomfited opponents
He spoke with sledgehammer directness
He suffers nothing to draw him aside
