What is the possible relationship between the two speakers? [br] [originaltext]

Interviewer: How many different countries do you think you have been to?
Man: Once I made a count of how many countries I’d hitchhiked through and it came to twenty eight. So if you add on a few more for those where I haven’t hitched, I imagine it comes to about forty by now.
Interviewer: About forty! And are there any of these that you feel you really would like to go back to?
Man: Two that I could actually live in I think. One would be the west coast of Canada because I think that had everything to offer. It was rich culturally, it was very bright, it had a very pleasant climate, slightly improved on Britain. It had the Rocky Mountains behind, loads of coastline, um, a lot going an both day and night, a large university and it was just near America if you felt like crossing the border. The other place I liked, but more for a holiday, was Sardinia, which I found was one of the quietest, most unspoiled parts of Europe that I have seen.
