Rob: Hello and welcome to the English We Speak. My name is Rob.
Helen: And hello, my name is Helen.
Helen: That sounds like my phone! So if something isn't doing what is should do then it's misbehaving?
Rob: Ha Ha! Well, you could say that. It's just like people. When they misbehave we can say they're playing up. Like this…
Helen: Children are very good at playing up; it's usually because they want attention.
Rob: Now, Helen, could I have your attention now please because playing up is also something you can say to describe a part of your body that's not working properly.
Helen: So it seems playing up refers to anything that's not working or behaving as it should. Now Rob, my leg's also been playing up so I wonder if you could give me a lift home in your car?
Rob: No way - oh it looks like my microphone's playing up now!
Helen: No Rob, it's you who's playing up - now switch it back on!
Rob: Oh, oh OK then Helen!
Helen: Let's go then. Bye!
Rob: Bye.
