When there is interpersonal conflict we are often discouraged because our intentions are misunderstood. What we must remember is that our intentions don’t count. The person you are talking with is not a mind reader. What matters is how are our thoughts perceived. An intention that does not translate into being a benefit to someone is a rotten intention.
Don’t let a single rotten word come from your mouths, but rather, whatever is good for constructively meeting problems that arise, so that your words may help those who hear.
