The street is lonely because it lacks the presence of people and activity. Streets are typically bustling with life and energy, filled with pedestrians, vehicles, and various forms of entertainment. However, when the street becomes lonely, it can be attributed to several factors related to vocation.

1. Lack of Job Opportunities:
One reason for the loneliness on the street could be the absence of job opportunities in the area. If the neighborhood or city is experiencing a lack of employment options, people may move away in search of better prospects. As a result, the street becomes empty and desolate.

2. Remote Work:
With advancements in technology, the concept of remote work has gained popularity. Many individuals now have the flexibility to work from home or any location of their choice. This shift in vocation can contribute to the street's loneliness as people no longer need to commute to an office, reducing the number of individuals on the street during working hours.

3. Night Shifts:
Certain professions require individuals to work during odd hours or night shifts. These jobs may include security guards, healthcare workers, or those involved in the hospitality industry. As a result, the street may appear lonely during the day when most people are at work and only become lively during the night when these professionals are on duty.

4. Seasonal Employment:
In some areas, vocation may be heavily influenced by seasonal industries such as tourism or agriculture. During off-seasons, when these industries are less active, the street may become lonely as fewer people are engaged in work. This can particularly impact areas that heavily rely on seasonal employment.

5. Work-From-Home Policies:
In response to the COVID-19 pandemic, many companies have implemented work-from-home policies to ensure the safety of their employees. This significant shift in vocation has led to deserted streets as people no longer need to commute to their workplaces. Instead, they can carry out their duties from the comfort of their homes.

In conclusion, the street can become lonely due to various vocational factors such as a lack of job opportunities, remote work, night shifts, seasonal employment, and work-from-home policies. These factors contribute to the absence of individuals on the street, resulting in a sense of loneliness and desolation.
