When people work the 9 to 5 rather than the typical 14-16 hour workdays. An hour lunch break may be taken on these days, but is still frowned upon. Some people may catch a "holiday" and become quite unresponsive. Stay away from these people.
Something thats impossible to enjoy at my house because every holiday ( Especially independance day) My father drinks heavily, throws his old vietnam uniform on, grabs his m-14, and fires at my neighbor who just happens to be vietnamese while he shouts " we won the war you brown cocksuckers! Burn in hell you motherfuckers!" Not the best time of the year.
