No he can't be wrong there. He knows Mini's age. Mini is in her mid teens. She is fifteen or sixteen years old, there is nothing odd in that. But Bondita, he just doesn't know her.
Mini is 15? That i did not know.I thought she is 18 at least.May be i missed.So she is 5/6 years smaller than Ani.
I was saying that Binoy does not know the actual age of bondi,may be he think her 10 from start,thatswhy he said that she will be of mini's age after a particular time.At that time i thought Binoy knows the actual age of Bondi,so i was surprised.
