My mind is open and my words are kind.

There's a reply most people have written at least once and not sent — sharp, accurate, satisfying to type. Deleting it is a small act of kindness with no witnesses and no thanks attached.

Open and kind aren't the same instrument. Open means you might be wrong about the person. Kind means that even if you're right, you don't need to prove it in the next thirty seconds. Most of the damage done between people is done by accurate remarks, delivered promptly.
