Otao is in the nurse’s office due to anemia.
Feeling better, he tries to go back to class but decides to take a detour to the deserted hallway. While walking in the quiet hallway, he discovers wet towels on the floor..
Back then, people used 
these to wipe their butts.
في تلك الفترة، كان الناس يستعملونها لمسح مؤخراتهم
Damals haben sich die Leute damit
den Hintern abgewischt.
C’était leur papier hygiénique
de l’époque.
In quel periodo
 venivano usati per pulirsi il sedere.
Elas, na época, eram usadas
 para limpar o bumbum.
