How did you enter my barrier 
without me noticing?
كيف دخلت إلى حاجزي دون أن ألاحظ؟
Wie konntet Ihr unbemerkt
meine Barriere durchqueren?
¿Cómo cruzaste mi barrera
sin que me diera cuenta?
¿Cómo has entrado en mi barrera
sin que me dé cuenta?
Comment as-tu pu passer la barrière
sans que je m’en rende compte ?
Come hai fatto a entrare nella barriera
 senza che me ne accorgessi?
Como entrou na minha barreira
sem que eu percebesse?
Как ты смогла…
пройти сквозь барьер незамеченной?
