i knew the ending was going to play out like this but..spoiler

I would have killed both kids.

When the girl was standing in front of the shocked parents, the mum came close to the girl, remember?
She was reaching out with her hand towards the girl and I really thought she wanted to strangle her.
But then she just pulled her jacket or sth like that.
Maybe she was really thinking about killing her but couldn't do it.

I had no idea the movie was going to play out that way. How horrifying that they ran her father down for nothing, even though it was a very bad idea to begin with.
