The Calendar power

I recently bought myself a calendar where you can write your to-do list for the day. For the past years I have used a free one, the University of Iceland provided them for free for its students. Since I moved to Denmark I haven´t had one on paper, but always used the calendar on my phone to schedule and organize things I need to do. But since Im a full time master student I decided it´s best to buy one paper calendar, not too big so I can always carry it around Looking through the pages it got me thinking...why do the weekend days have smaller empty lines than weekdays?

Yes I know the obvious answer is because they are free days, time for relaxation and chill out, or partying. But I´m wondering, ok if you are a full time worker, wouldn´t you actually use the free days to express and enjoy yourself and make the most of your time away from work/school duties? You don´t have to go small, go big, do something big, overfill the few empty lines in those calendars

Another thing connected to this "weekend" discussion...people often ask "What are you doing?" and let´s say it is Friday or Saturday. And I´m not doing anything special but chilling, because I don´t feel like it or don´t have the energy at the moment. Then starts the convincing " Oh come ooooon, it´s Friday/Saturday!". I´m thinking ok, but why do I have to obey these dogmas that it is weekend and therefore I need to be partying?! Why does it all have to be according to the "weekend rules"? I want us to be able to party or enjoy friends company in a party environment whenever we feel like it, even though it´s Monday evening, or Wednesday. It is way too structured and impersonal. It´s weekend guys! You have to obey the "weekend rules " and do what you are supposed to do on weekends! Blah...
