Did the mother with the stroller need to apologize?

Why did the woman with the stroller apologize?
It happened on a weekday afternoon while everyone was waiting for a train at a station platform in Kanagawa Prefecture.
Suddenly there was a woman’s shout, and a man turned around in surprise. Then he saw that the front wheel of the stroller pushed by the woman was caught between the train and the platform. He rushed to help, but could not get the front wheel out. He wondered if he should leave and press the emergency stop button, but soon a station attendant rushed to the scene and with a little help, he was able to pull the front wheel out.
The train was not delayed and nothing serious happened, but what surprised him was that no one came to help, even though there were many people on the platform and in the train. What surprised him was that no one came to help, even though there were many people on the platform and in the train. Not only that, many people gave the woman a cold stare, as if they didn’t want the train to be delayed. Another thing that struck him was that after the front wheel came off, the woman bowed her head saying, “”I’m sorry,”” as if she was really sorry.
It was not until he saw the frightened expression on the woman’s face that he understood what the difference in “”atmosphere”” was between Japan and other countries when it came to child rearing.
When a father was raising his child in Japan, he would choose places that were stroller-friendly or safe for his child to go out, always worrying about whether the stroller or the child would bother others. However, as he and his children spent time in the U.S. and Austria, these worries naturally disappeared. He went from “”looking for a safe place for the kids to spend time”” to “”a life where kids and adults can enjoy together.
