Please don't read the tittle and read the Phrase 2 times with natural speed before read the situation about it. ^^ Thank you very much.
"Hold on, hold on. Start at the beginning."
Situation :
The child that you babysit had some kind of accident. He's upset and crying. He's trying to tell you about the accident, but it doesn't make sense. You tell him to start telling the story again in order.
