Some people, consciously or unconsciously, go out of their way to annoy us. They provoke in us a genuine personal dislike. Our rationalizations for our feelings and assessments can be singular or plural.
We can soften our position with small considerations of anything we find valuable in them. It could be we like some of their intentions or abilities. We could value some of their contributions. Most mindfully, we can curiously explore more about any hidden goodness.
