What should young people in the lower berth of the train do when they meet pregnant women in the upper berth?

My personality belongs to people. I respect a foot, I respect a foot. If you don't respect, I don't care who you are. Since the most convenient thing in my hometown and town is the train, I have taken many long-distance trains for so many years since I started college, most of them are sleeping cars, and I have met many people who asked to change places, both with and without consent. Let me give two simple examples. A 30-year-old mother with a young child looks very honest. When she asked me, she still felt a little embarrassed and felt that it had caused me trouble. She was embarrassed when she said it, but it was just that the children were too noisy and it was really difficult to climb up, and so on. Besides, she has been driving for a long time. She has been sitting by the window and has seen her look at the upper berth many times, but the child has been crying. She said to make up the difference, but I refused. Then she kept boasting that she had met a good man, took out some dried pumpkins and invited me to dinner. We talked for a long time on the boring train. It was a wonderful trip and everyone was very happy. Actually, it doesn't matter much to me whether I climb the upper bunk or not. When I was at rush University in Spring Festival travel rush, I got into the car with great difficulty and found that the place next to my luggage was already full of other people's luggage. Although my bag is not big, it is in the way on the bed, so I try to move the luggage that others haven't tidied up, hoping to find a gap to put it in. At this moment, a mother with a child in her arms came over, and her husband should be behind. When she saw it, she shouted, don't touch my things. In that case, I won't move. When I found out how to move it, I still couldn't find space. When I was about to give up, my mother's husband told me that if he was willing to change the bunk with his wife's bunk, he would move a place for me, otherwise he wouldn't move. I thought it was funny, so I was threatened. I dumped him coldly, so I put things on the bed. Who made the lower berth for me? I am very happy. I don't think she will refuse to hold the baby if they exchange kindly, but if he does, then I really won't. Therefore, in fact, it is not a question of bunk beds, whether to make up the difference, or whether I am willing to climb up and down, but a question of respect. If you want something from me and you respect me, I will choose to respect you instead of moral kidnapping or threats. This society needs everyone to start from themselves, and there will be qualitative changes. What we can do is to do well, not to do evil.
