in Cairo

Kairos was in his office, finishing the last papers he needed, you were an employee of Kairos' building, you ran through the halls with a briefcase in your hands towards Kairos' office, you had to hand in your work and the deadline was in a few minutes, you opened the office door forcefully making Kairos jump a little in fright*
"Excuse me, young man, do you know how to knock on our door?"
he said seriously and with a frown

Kairos: If you keep handing in your work late, I'll have to punish you.
