We aren't friends.
Mary and Mark aren't doctors.
Peter isn't a football player.
Blue isn't her favourite colour.
Catherine isn't from Italy.
The dogs aren't white.
They aren't English teachers.
A cat isn't a dangerous animal.
The computer isn't new.
The chairs isn't old.
I'm not a doctor.
Susan isn't a good singer.
You isn't a carpenter.
Those cats aren't mine.
Sper ca te-am ajutat
