Is the tongue a weapon?
Tongue is dangerous weapon
140 words in Jacobus 3

The tongue is a dangerous weapon. As people, you can do a lot of harm to each other. The words a man utters can make and break the fellow man. But, above all, breaking can last for years, can last for decades. These words can completely destroy a human life (especially in the spiritual, psychological sense).
All those words, all those sounds are created by the attitude of the tongue. The tongue is sometimes contracted while speaking, and at other times you speak with a smooth tongue. All this causes a response to the hearing in one way or another. In other words, the tongue influences the interrelationship between people.
And what do you think happens when you stick your tongue out to someone else? Will the other person feel taken seriously? Loved maybe? You can seriously ask that, seems to me.

A spin of thought @140woorden of course can not do without processing the keyword of the month, business names .

But you're absolutely right, having a tongue like razor cuts ugly wounds.
