Me : That's a bit left field. I normally talk mapping. Why do you think an alien race would be interested in contacting us.
X : We'd be interested.
Me : Yes, but that's because they're exciting. We wouldn't be.
Me : If you're an alien race talking with billions of other alien races then I could imagine in the great vastness of space that Earth would be very dull indeed. The only people who would be excited to talk to us would be other races looking for races to talk to.
Me : Do you live in the UK?
X : Yes.
Me : Do you get really excited by every new person born and go out of your way to talk to them?
X : No
Me : Well, there's your answer. Probably.
