Convert this into reported speech:
“Hello, Mother,” Farah greeted her mum as she entered the door.
"Where is your sister?" Mum asked anxiously.
“She stopped by to get ice-cream on the way. She’ll be around in a few minutes,” Sarah announced casually.
“How many times have I told you to not leave her alone, she’s young!” Mum shouted frustratedly
“Oh, I’m sorry, Mother. I’ll be careful next time,” apologized Farah immediately.​
