What does it mean to feel bleak on rainy days?

This is because the rain is continuous and gloomy, people are in a gloomy environment, and their emotions are easy to suppress, so they will feel sad. In the education we received from childhood, whether in songs or articles, rainy days are associated with words such as missing tears, crying and sadness. Over time, you will feel sad. Ask a child who is only a few years old, will he feel sad when it rains? Of course not. Ha ha.
