Late night

Charms of late night..why do we want to be up late alwaysss very late in the night. I belong to the group who are not disciplined and particular about the time they go to bed..why does darkness has such allure for me. why does my heart thinks the fastest at 1 in the night..why do i want to talk to a thousand people at 2 pm. Why do we sleep at night? Who decided that? why do we blindly follow what was decided ages back..why do we question almost every rule in the book but never question our biological clock..i really wish i could break away from this discipline and work at cold nights...party in moon light, have long lunches under the stars (Yes..Lunches)...Why can we not have lunches at night???
