When you feel sorry for the other person, calmly convey your emotional state to the other person.
How should I express it when I hear a disappointing story from the other person? Should I raise my voice and say, “How dare you talk to me like that”? Or should I calmly say, “I feel a bit sad when you say that”? When expressing feelings of regret, it is better not to speak in a blaming tone, but to convey only your emotional state to the other person.
If you feel sorry for the other person during a conversation, it is better to convey your feelings to the other person right on the spot. Then the other person will know how I felt and be careful with his words. If you can't express your sad feelings to the other person and keep them in your heart, negative emotions will accumulate in you, and as time goes on, your relationship will become uncomfortable. It's better to work it out before feelings build up, before the relationship becomes uncomfortable. This is the wise conversation of a mature person.
