I'm really sorry for 
coming uninvited, though.
.لكنّي آسف للغاية للمجيء دون دعوة
Tut mir echt leid,

Y perdona por venir sin avisar.
Y perdona por venir sin avisar.
Je suis désolé
de t’avoir suivie comme ça.
Però mi dispiace davvero venire da te senza invito.
Desculpe mesmo por aparecer assim.
Ты извини, что я без приглашения.
