Many is the person I have seen fall into sin by speaking, but scarcely ever have I seen anyone do so by staying silent. The reason is this: it is far harder to know how to stay silent than it is to know how to speak. I realize that most people speak simply because they have no idea how to be silent. It is a rare thing for anyone to keep silent, even when there is nothing to be gained by speaking. It is a wise person indeed who knows how to keep silent.
--St. Ambrose of Milan
It's a little funny, but so true. I often forget that "there is a time to be silent and a time to speak." Have some fun in the silence!
