There is nothing more ominous than silence.
The Bowl Judgements in the Book of Revelation are preceded by a half hour of...silence.
Silence when used in the right context can get someone’s point across better than words alone. When I was a kid and did something wrong, my mother would say “Wait till your father gets home”. After that, silence. And when he got home there was not a word for about 15 minutes or so and then punishment came. It seems like hours. BIBI slammed this one out of the park.
