What is the psychology of people who don't cry or feel sad after the death of their loved ones?

The ancients said: Great sorrow without tears. Sadness is more terrible than death! At that moment, the whole person was an empty shell with nothing in it! What is the psychology of people who don't cry or feel sad after the death of their loved ones? Let me tell you something about my friend:

The first one: When my mother died, just like you, I didn't realize that I didn't have a mother until I went home on holiday after burial. I am a child without a mother. At that time, I was in the college entrance examination. At the most critical time in my life, my mother was gone, and there was something wrong with the college entrance examination. Sometimes I think to my mother's portrait, what would my life be like if she were still here?

The second one: I wanted to cry almost an hour before my grandmother died. Suddenly want to cry for no reason. At that time, I thought my grandmother was in good health and had a few years to live. ) I thought it might be the saddest cry in my life, and I cried for no reason. When I calmed down for about half an hour, they came to tell me that my grandmother had passed away. From the beginning to the end of grandma's funeral, I didn't shed a tear and remained expressionless. I haven't cried since then Now that I think about it, maybe? Oh, I have a grandmother. She is dead! ? This feeling.

Third: When Grandpa died, my sister sent me a message telling me that I refused to believe it at that moment anyway, so I asked for leave to go home until the funeral was over. Later, when I went back to school, I suddenly felt empty when I was in the self-study class. I realized that there is no such person in the world, and I can only live in memory. Then I secretly cried for a few nights, hoping grandpa would be fine there.

Fourth: I was the same when my grandfather died. I was a sophomore at school. Suddenly one morning, the class teacher called me out and signed a leave of absence to let me go home. He didn't tell me that my grandfather died. He just said I had something to go back to at home. When I got home, I didn't know that my grandfather had passed away. I didn't cry until the last day of the funeral, and I really didn't feel sad. I feel very cold, and I thought, maybe it's because we don't see each other often (my grandfather and my father have a deep contradiction, so I don't often come to my house. I stayed at school for a month and then went home for two days), but after my grandfather died, I often thought of him. I often think of some small things I got along with him when I was a child, and sometimes I cry, but I still don't feel very sad. I wonder why.

I think this may have something to do with growth. As we grow older, we will experience all kinds of difficulties and hardships, and our endurance will continue to improve. To a certain extent, tears can basically be controlled in front of people. Tears are not the only explanation for sadness. So we all grew up later. In the future, you may suddenly want to cry, or cry, at a certain time, for no specific reason. It may be that the body reflex arc is long, or it may be released because an event suddenly touches you. That's because you didn't leave someone who really hurt you. Although they are close relatives, the relationship is close, the distance is far, the distance is close, and the physical distance and psychological distance are different. Some relatives, how hard to meet, have little influence on your living habits. Blood relationship is the bond between people, but the key to close contact between people is emotional voice and getting along with each other day and night. In addition, the age of the elderly and the way of death are also influencing factors. ?
