Some schoolboys are making a commotion in front of Tatsumi's apartment. They leave immediately when Tatsumi calls out to them. Looking down, Tatsumi discovers a conch rolling near his feet.
I'm really sorry for barging in 
on you without an appointment.
أنا متأسف للغاية على إقحام نفسي بينكما هكذا دونما موعد‏.‏
Tut mir leid, dass ich ohne
Termin vorbeikommen bin.
Siento mucho visitarlos sin previo aviso.
Siento mucho haber venido sin previo aviso.
Je suis vraiment confus
Sinto muito por invadir sem convite.
