Night refers to the time of day when the sun is day, and each day ends in night and also starts this way. Night quotes show that some people love this time while others dread it. The darkness which indicates that night has fallen can make some individuals nervous because it can be difficult to see if you have insufficient light. Some animals hunt at night and sleep during the day, and this is especially common in tropical regions and very hot areas where extreme temperatures are frequent. Most people sleep at nigh but there is a small percentage of the population that works the night shift, and in this case the worker toils while it is dark and sleeps when the sun is up instead of following the usual schedule.
