Anna whispered it slow to made sure Daniela's father couldn't hear it. Even though it wasn't the best words that she could give but Anna didn't know the better words except that. She always had a problem with choosing the right word to use.
In Anna's head, she also questioned if that's the right word to use but it had spoken so she hoped Daniela would understand the meaning and her intention of saying those words. It's happened within a second and the chances really small but she would see with Daniela's reaction.
Turned out Daniela didn't have an idea what's the meaning behind it. Anna was saying something crazy and it out of the blue. Again, Daniela was surprised that Anna would be saying such a thing but also everything had been so crazy and full of surprise.
