Waking up on a weekday and having no homework, no paragraphs to memorize, no kanji to practice, and no need to hurry feels weird.
Suddenly the mind has empty spaces, and those empty spaces start filling up with memories of the food you used to eat, the ones you love and miss, the weather you were used to, the texture of your own pillow…
Which is why you must strive to reconquer those invaded spaces with new sights and experiences. After all, when you go home, you will miss this place too.
