There are people who think they know what a person is doing just by making inferences that have been incorrectly arrived at. Even worse, is when such false inferences are being talked about thereby creating an untrue picture of things. Worse still is when people construe mundane actions and blow them out of proportion, giving them different labels.
The truth about wrong inferences is that they are destructive and unhealthy.

So, as a rule, it is always good to tame the tongue:)
