...is a teachable spirit.
As children we are (hopefully) taught manners, and how to interact and share with others. But over the course of time, and perhaps in given situations, we need a bit of retraining to behave properly toward other people.
For that, we must be teachable. If a person believes they were through with being taught once they emerged from childhood, they are over-looking the fact that we humans are a work in progress---teaching and correction are part of our lives. Who hasn't received a speeding ticket or some other traffic violation--a reminder that there is a speed limit or other law for a specific reason?
Be teachable. Be open to gentle correction. Be willing to grow into a better human being.
