Purple Realm

Ok, so we were just sitting here, playing Left 4 Dead, when someone knocked at the door. I decided to answer and was greeted by a scruffy man with an Ipsos Mori clipboard and identity badge.
He introduces himself on behalf of Ipsos Mori and the BBC, and asks if I'd mind taking a survey about listening to the radio.
I tell him I never listen to the radio - that is a truth - and he says that it's okay, it's all part of the research. So I say "okay".
Mik comes to the door and the man fills him in. He asks if our block of flats is student accommodation - I tell him it is strictly no students.
So, he says "I'll leave this with you, and pick it up on Monday then?" proffering a paper booklet - the survey.
"Yes, that's fine," I say, and smile.
He then asks which of us will be filling it in, seeing as they need the age and sex of the person.
Mik and I look at each other, and we audibly come to the decision that it doesn't really matter, we'll figure it out when we fill it in. I go to take the form and he pulls it back.
The man then looks... Well, like his feelings are hurt, raises his hand and says, "No, it's fine. I can see you're not really interested!" has a face like I just shot his dog or something, and walks off!
