Caring personally involves nurturing the relationship you’ve built prior to giving feedback. If you’ve consistently shown that you have this person’s best interests at heart, then you’ve laid the groundwork for that person to be receptive to your constructive criticism. On the other hand, if you don’t have much of a relationship at all, or worse, have a negative one, your feedback is not likely to be accepted. It is too easy at that point for the receiver to disregard it.
