Working late at work, with the office mostly deserted, it can be easy to imagine things that aren't really there. But is it really just your imagination...?
Who is it? Who's there?
من؟ من هناك؟
Wer, wer ist da?
¿Quién? ¿Quién es?
Qui c’est ? Qui est là ?
Chi è? Chi c'è là?
Quem? Quem está aí?
Кто? Кто это?
