This shows that in real life, when something comes to an end, your girlfriend can't find its basis. The end and the beginning are like two different circles. When you leave this circle, you enter another circle.
Going to work is one environment, and getting off work is another environment. The function of the punch card machine is to show whether the person has come on time. In other words, she should leave this circle and walk into another circle at the same time, but she can't find the direction and get lost. At this time, the sky opened its mouth, giving her snow, comforting her and calming her down. The hole in the sky is an exit, but it is not a way out. Although this "day" has given her comfort and calmed her down, don't worry. Without giving her a way out.
