I have to say, I take some kind of perverse pleasure in watching the truly obnoxious, demanding people. Like the ones who look at a million-dollar vacation home and say, “Well, it’s not the kitchen of my dreams…” There was a lady the other day who kept raising the bar higher and higher and finally the agent said, “We’re going to have a hard time finding what you want in your price range!” You got the impression he wanted to lock her in one of those too-small closets and go off and leave her there.
There was a 25-year old guy several years ago who was a real party animal and he was looking for an apartment in downtown Madrid (that his parents were going to buy for him!) where he could enjoy the night life. Finally, he found the outrageously expensive, but charming apartment he wanted, and when they did the re-visit at the end, he had gutted the whole interior, and now it was this stainless steel, black and gray, super-slick bachelor pad . Ugh. 
There was a lesbian couple who bought a huge, beautiful apartment in Sweden with those porcelain stoves that run up to the ceiling. The apartment had giant windows and many charming vintage features- that they left alone!
It seems to me that generally the gay male couples are particularly loving and cordial to each other. They seem more like peers than many (not all) of the hetero couples. The hetero military couples also seem very loving and supportive- I guess from having plenty of experience moving.
There was one gay couple where one guy was sort of cool and detached and the other seemed to be a real hothead. EVERY house they looked at, the hothead voiced many loud objections- this didn’t work, this was dated, have to pull out every cabinet in here and gut the place! He seemed so domineering and used to getting his way. He was always shouting down the cool one. But they wound up in the house that the cool one wanted. This made me think (and maybe I’m reading too much into this) that the cool one understood that the hothead needed to blow off steam, rant and rave, but they both knew that the cool one was level-headed and probably capable of making the more rational decision of the pair.
One that really sticks in my mind was a couple where the guy was white-haired (probably in his late 60’s) and the wife was Asian, and they had two little girls about four years old. They were looking for a vacation home on some island. I don’t remember how big the house was that they wound up with… maybe 8,000 sq. ft?.. but it was enormous, and cost a couple of million. There was a lower level family room that alone was probably 2,000 sq. ft. and it was wall-to-wall with the girls’ toys and Barbies. The really odd thing was that they had a live-in maid, also Asian, and the maid was the WIFE’S SISTER. She referred to her as the maid, and in a scene at the end, the wife was showing her how to operate the dishwasher.
What I like best is the peek into other people’s lives that are so different from mine. About five percent I think, “I’d like their lifestyle,” but the other 95 percent I just stare at and shake my head.
