How do you know that the person is insensitive?

You can identify insensitivity in a person through their responses to others' feelings or situations. If they consistently dismiss or belittle emotions, fail to offer support during difficult times, or make inappropriate jokes at the expense of others, these behaviors indicate a lack of empathy. Additionally, if they frequently interrupt or show disinterest when someone is sharing personal experiences, it further highlights their insensitivity. Overall, a pattern of neglecting others' emotional needs signals insensitivity.
