It's interesting that their love objects are all constructed or engineered things, rather than, say, a rock, or a pillow.
Also, of all the things that made me feel uncomfortable, strangely the worst was probably the two women arguing over who had it worse, the oppressed citizens of communist East Germany or the woman whose parents didn't love her. I understood the point she was trying to make, but that was kind of the wrong venue in which to be making it...
