Down with the kids

Helen: Hello. Welcome to The English We Speak with me, Helen ... 
Rob: ... and me Rob. Hi!
Helen: Rob, I like your trainers, very cool ... and look at your designer jeans. Trendy! Rob's looking quite trendy today—for a change!
Rob: So you like them then?
Helen: I do but ... it's not really what someone your age normally wears.
Rob: I see. But don't you think it makes me look cool and fashionable and ... younger?
Helen: Erm ... 
Rob: I'm just trying to get down with the kids.
Helen: The kids?! You're down with the kids? Down where exactly?
Rob: Oh Helen, keep up! I'm not going anywhere. I mean I'm keeping in with the kids. I'm in tune with the younger generation—yeah!
Helen: So Rob, to do this you have to dress like a teenager?
Rob: Not just that. I share the same interests as young people. I listen to their music on my mp3 player. Like this.
Helen: Could you turn that down please! So you're acting young when really you aren't! It seems getting down with the kids is about behaving like them. Well, you are certainly a big kid Rob! Let's hear some examples of people using this phrase.
My Dad's bought a new skateboard so that he can be down with the kids!
I almost broke my neck snowboarding on holiday but hey, at least I'm down with the kids.
Helen: So Rob, what else are you doing to be down with the kids?
Rob: Hey Helen, doing things like chillin' and being where it's at.
Helen: Rob not all kids talk like that.
Rob: Oh right. Well, I've got some rollerblades so I can blade round the park. The only trouble is ... I can't seem to get them on ... Ouch, my back!
Helen: Are you OK? It looks like Rob has a bad back, so he won't be down with the kids for a while! Do you need some help?
Rob: Thanks. I think I'll just put my slippers on—much more comfortable.
Helen: Remember, being down with the kids can be hard work. See you next time. Bye bye!
Rob: Bye. Ouch, my back! Helen, could you just put that slipper over there please? Thanks!
