Well we probably went through this during every holiday where most of us will be a sloth. What i meant here is holiday is a day off. a day off means an off day for us. so the ideology(ies) of where students MUST study and such things done in schools ain't parallel to the concept of day off.
Enjoy it before it's too late because as you are imploring the adult life time by time and starting to resign from the adolescence life, you will feel no more better than staying at home, lazing like a sloth. You will not get the oppurtunity that time. To get it, a working time of years are demanded. easier to say, retirement.
But being in retirement sectors mean you are getting older.Eventhough you will feel relaxed but remember being gold is no gold to be compared with the fun of sloathing now. So held your head high, focus in class, study smartly(hardwork is needed), get good grades(very) and there will be no worries during your holidays.
Then you can say it loud(please.not YELL), "My day off is my OFF-DAY!"
