I like all three of you. You're the most 
precious people I have in the world.
Ich liebe euch alle drei,
ihr bedeutet mir die Welt.
Siete tutte e tre le mie persone preferite
a cui tengo molto.
Gosto de vocês três. Vocês são
muito importantes para mim.
Я вас всех люблю. Вы самые
дорогие для меня люди.
