Help when there's a problem

Cèlia.- Marina, what's happened? Are you OK?
Marina.- No, I've burnt my hand.
Cèlia.- How did happen?
Marina.- It was an accident. I put my hand on the cooker.
Cèlia.- Oh, right. Do you need help?
Marina.- No, I think it'll be OK.
Cèlia.- Mmm. Maybe you need to go the chemist's and to see a doctor.
