[ cheers ] >> when they were launching this life boat and after she poured the champagne, william bowed to her with her hands like that, in acknowledgement that this was her first public engagement and she did it brilliantly. >> reporter: yet their lives are not dictated by palace and protocol. unlike past royal couples, william and kate settled far from london's palaces in a small house in remote north wales. >> william is an r.a.f. search and rescue officer. it's a dangerous business. he plucks stranded hikers off mountaintops. meanwhile, kate is kind of keeping the home fires burning at their little house in north wales. >> there'll be no one cooking dinner. there will be no one cleaning the brass. it's going to be different than charles and diana. there will be no big stately home. not yet anyway. he's going to go to work, do his shift, come home, chill, watch tv, probably go and get a video, get some pizza. that's the way they are going to live their life. >> it was the way kate grew up in rural bucklebury. normal, quiet. once criticized as too common, it may be the very thing that helps keep this royal couple together. >> a lot of the aristocrats are probably the least able to deal with that kind of thing. they didn't often have a firm grasp of what it was like to live in the real world. i'd say that she was much better equipped to deal with the pressures of royal life than the average aristocrat was. >> ironically. >> ironically. >> unlike diana, of course, kate middleton has been with william now nearly eight years, so has had quite a lot of time to reflect and say is this a lifestyle i want? this is what i'm going to get for the rest of my life. in that sense she was a considerable way ahead of diana in understanding and knowing exactly what was coming her way. >> reporter: for william history would not repeat itself. >> it's kind of almost why i had been waited this long. i wanted to give her a chance to see and back out if she needed to before it all got too much. i'm not trying to learn from lessons done in the past. i just wanted to give her the best chance to settle in and see what happens on the other side. >> reporter: do you think everyone's got it right this time? >> i think finally they have it right. and i think it all is because of diana. if diana hadn't shaken things up the way she did, if she hadn't made the monarchy collectively look at itself in the mirror and see what they were doing wrong and what they could do right, none of these changes would have happened. and i think the true catalyst for all this change now is kate. because in essence, you know, she's going to be the first true people's princess. >> reporter: the people's princess, like diana before her. but unlike diana, prepared for what lies ahead. a royal couple living life on their own terms. making their own way to the day
