I am sure many of you have experienced coming to school or office late especially around the months of December to February because we know  how nice it really is to sleep during the cold season. It is really cold in the morning and even with the sunrise, things seem still gloomy and dark. That has made us stay late in our custom mattress or bed. My son even asked me one early morning why I was trying to wake him up for school as he thought it is still night. But those who came late for the whole year cannot blame the weather but rather their prolonged habit.
