A link between Week days and weekend is Friday. There is this exiting feeling whenever it comes even when there might still be work to do the next day. To some, Fridays make them come alive. The mind naturally is configured to be relaxed on Fridays.
The day automatically reads let us have fun. For most office workers, it marks the end of office work load for that week.
When Friday comes we just want a break and some dose of fun.
