another thought

I'm writing down this thought before I forget it so here it is
Why do people here in England an the rest of the world wake up early in the morning and sleep early in the evening? I asked myself this question as soon as I got here. Shops and businesses close doors around 6 p.m. while back home everything starts at 5 p.m. and life starts at night; people go out at night, shop at night, see friends at night, even some of them go to school at night! I had a hard time adjusting at my first few weeks in this town. Back in Saudi Arabia we didn't have lunch beaks. Everything starts very early in the morning around 6 a.m. sometimes before the sun even rises. I remember having breakfast with my parents at 5 am then starting my car on my way to school before 6 am and then driving for an hour in an open space where I can see the sunrise through my window every morning. Oh my God I miss those days.
At noon everything stops and people return to their homes to have a big lunch with their families and then it's nap time! At this time of day every human being living around the tropic of cancer is asleep! When I was little, I wanted to defy this law but I couldn't. I fell asleep as soon as I got home from school! At 5 pm. when the sun becomes less aggressive, everything starts again and the empty six-lane road becoms a grid lock!
Finally, at late evening when everyone return to base the family gathers before having a light supper which can be around 11 or 12 pm. and then everyone get to their rooms preparing for the next day. But here I feel that everything is the opposite. What do you think?
