I can tell you that some individuals may have home lighting circuits with multiple switches and have a habit of checking that they are all in the "DOWN" position at night, even if the lights are off.
This behavior could be related to safety concerns or habits developed over time. Some people might do this to ensure that all the lights are off and not consuming unnecessary electricity, or to create a sense of peace of mind before going to bed. Others may have developed this habit due to personal preferences or because they were taught to do so by their parents or caregivers.
Habits like these can be a part of a person's daily routine and can vary from individual to individual based on their upbringing, lifestyle, and personal preferences. However, it's important to remember that not everyone engages in the same habits or routines, and each individual's approach to their home lighting circuits may differ.
