.لا لصديقه ولا لشريك حياته ولا حتّى لعائلته
Weder Freunden noch Partnern

Ni a sus amistades, ni a sus parejas,
Ni a sus amistades, ni a sus parejas,
que nos amis, notre partenaire
et notre famille ignorent.
Di fronte al prossimo, 
che si tratti di amici, partner o famigliari...
Nem para amigos, namorados
 e até mesmo familiares...
И от друзей, и от возлюбленных…
и даже от родных.
