The Sunday Evening guy is at the center of a person's universe. He is the central pivot around which everybody rotate and live their lives. He holds the key to the overall well-being of that universe. He is the key transition point between a person's life and person's work. Sometimes the birth of this guy is premature. He is born immediately after people take a bath on Sunday morning (read as afternoon). The ancient rishis uvach'ed out a proverb that defined the Sunday evening guy. They said "if you take a bath, Sunday is over, the weekend guy dies and the Sunday evening guy shall be born". Which is why the weekend guy is so afraid of taking a bath early on a Sunday morning. It is a curse some weekend guys live with. The weekend guys who survive the bath, live long enough to eat a hearty meal on a Sunday afternoon and take a 2 hour nap. That is as far as any weekend guy gets to go. The guy who gets up after that nap is the Sunday evening guy. There is no turning back after that.
Sunday evening guy is a pensive guy. You could say that he has got that tinge of sadness about him. He rues his career, his ambition, his work and his entire life. Legend has it that Sunday evening Isaac Newton initially wrote his first law as "An object will stay at rest and at extreme incredible intertia unless a cheap dastardly unwanted massive humongous force acts on the particle against the particle's wishes". The Monday morning Newton got into a lot of trouble for that and so it was changed eventually. If the Sunday eveing guys ran the world they would halt all progress and extend the Sunday evening up until Thursday. It is the pleasure of being the Friday afternoon guy that will eventually stop them from extending it all the way.
Now, that does not mean that the Sunday evening guy is an unhappy guy. Sunday evening is that nexus of the universe where a person experiences an uneasy mixture of sadness and happiness. Sunday Evening guy's mental state is similar to that of a prisoner who experiences a conjugal visit before being sent to the gallows. The danger of what is to hit that person on Monday morning at school, at work lurks in the corner of the mind. However, there is peace for the moment. You don't have to deal with it now. The real world has been suspended for now.
In the days where Friday/weekend/Sunday Evening guys didn't have the 24 X 7 satellite channels, Doordarshan's Sunday evening movie was culmination of a series of rare but valuable entertainment events for the weekend that began with the Friday night guy watching Oliyum OLiyum. The Sunday evening guy peacefully loses himself with a walk in Marina Beach, maybe a light tiffin at Woodlands Drive-in before he quickly hurries back home to watch the movie. He might get to see a really bad movie but the Sunday evening is a period of serenity that will be unparalleled for at least a week. In today's world, the lives of weekday, weekend, Friday night guys have undergone massive changes whereas the changes to Sunday evening guy's life has been minor. You could go as far as saying that the Sunday evening guy's life has become less peaceful. He does not like to be surprised on Monday so he watches a movie on Sunday afternoon and spends Sunday evening catching up on email and arranging his Inbox. Sunday evening guy may experience a few minor lifestyle changes over time but the essence of the Sunday evening guy will remain for eternity.
