The increase of low-headed people in the subway has brought many problems. When taking the subway, more and more people play mobile phones, which brings many problems. I sum up these problems in one point: I don't live in the present. When taking the subway, what we should do is to take the subway. If people concentrate on taking the subway, then people are taking the subway, and there will be no problem that other passengers are hindered by watching TV dramas on their mobile phones while waiting for the subway. However, I have seen people reading while riding. Although the man is reading a book, it won't hinder others. This makes me wonder: why do people who read books in the car don't get in the way of others, but people who watch TV dramas in the car get in the way of others (for example, because they can't feel someone getting off the bus with headphones plugged)? Just because one is plugged in and the other is not? Or is it related to what you saw? Yes, maybe part of the reason is related to the content. Because most TV dramas nowadays are too violent, such as family conflicts and so on. Imagine that you are wearing headphones in the car and watching a fierce family conflict drama. When someone reminds you to stop others from getting off the bus, there is a greater chance of conflict than you. Even if it's not a conflict, I'm sure I won't feel comfortable under the influence of that kind of conflict drama.
