Empathy is the ability to understand the emotional life of another person, almost in all its complexity. This does not mean that we share the same opinions and arguments that justify the state of the reaction expressed by the other person. It does not even mean being in touch with the way of interpreting situations with the emotional burden of the interlocutor.

Empathy is related to other things to active listening, understanding and emotional support. In addition, empathy implies having the capacity to differentiate between the affective states of others and the ability to take a perspective, both cognitive and affective, with respect to the person who expresses his emotional state.
