That was for the best !!!

Dan	The parents of children in our street are a lot less worried these days.
Chris	Why's that ?
Dan	One of the neighbors had a very fierce dog which scared everyone. Last week it bit one of the children so badly, she had to be treated in hospital.
Chris	That must have been an awful experience for the little girl. But why did you say they are not worried now ?
Dan	Well they complained about the dog to the police and the police forced the owner to put it down.
Chris	Oh I see. Well I'm sure that was for the best.
