Answer:
Old Woman: (angrily) No, I will not stand for this. How dare they treat my granddaughter like this. (to the boy and girl) Don't worry, I'll take care of everything.
Boy: (anxiously) What's going on, grandma?
Old Woman: (putting down the phone) That was your school. They're saying that you've been bullying a girl in your class.
Girl: (frightened) No, it's not true. I didn't do anything.
Old Woman: (calming down) Don't worry, I believe you. But we need to get to the bottom of this and clear your name.
Boy: (firmly) I didn't do it either. I'll do whatever it takes to prove it.
Old Woman: (nodding) That's my boy. (to the girl) And you, young lady, you stick by your brother. We'll get through this together as a family.
Girl: (nodding, holding her toy frog tighter) Okay grandma.
