People who speak crudely and speak words without a coat of sugar actually signal honesty. The abrasiveness of their language and words may prove displeasing and even discomforting to you to a certain extent, yet these people are actually being honest and you can also see them coming from a mile away.
On the other hand, people who speak sweetly and speak words coated with sugar yet lace their meanings with poison are the true threat. These people are dishonest and you will never see them coming.
