On Monday, when Sarah is on her way to home after her vocal course, she can't help but noticing Derry at his terrace.

Sarah: Hi, Derry! What are you doing?

Derry: Hi, Sarah! I'm trying to fix this iron.

Sarah: What's the problem?

Derry: It's broken.

Sarah: May I help you?

Derry: Oh, that's would be great, thanks. Do you know how to fix it?

Sarah: I think so. My father had taught me. We had the same problem with the iron at home. The first thing we have to do is to make sure the power is on to the outlet.

Derry: I think I have plug the cord tightly. So, it is okay. 

Sarah: Then, check the electrical cord, in case there is some broken.

Derry: I think it's okay, as the light is on.

Sarah: Well, then you have to check the thermostat. It is inside the iron.

Derry: How can we check it?

Sarah: Of course, we have to open the inside and replace it with the new one.

Derry: Sarah, you are amazing. I am a boy, but I am not used to do it. 

Sarah: Thank you.
