Desis love placing people. The placing exercise is all about identifying the social, economic, intellectual, spiritual, aesthetic class to which the person belongs. Perfect strangers with whom there is no business what so ever are subjected to this perpetual exercise. Desis are so good at it that is ingrained into every single aspect of their lives starting with their very names.
Indian names are very much like IP addresses. An Indian full name can give you the ancestral village name, caste (sometimes sub caste), the generation, linguistic affiliation, the professional background, and the exact social class to which the person belongs etc. Desis are very good at parsing these names and placing them in the exact social strata or geographical location they come from.
Indians also use social appearances, attire and other paraphernalia like markings on forehead, number of threads in a sacred thread, design of rings and other jewelry to place them in a caste or a sub-caste. Brand names of clothes and dressing are used to put them in an economic class.
Cellphones and cars are another biggie. The size, color, brand, the size of the screen, the resolution of the camera, the ringtone on the phone, the cautiousness with which the phone is handled, the frequency of changing to a newer device are all signals to flaunt their class and desis are adept at reading them. Desis make it a point to include pictures of themselves holding expensive cellphones or standing beside high end cars in their portfolio.
More recent cues to place people have been people’s accents, hair styles, visa statuses, the countries they have been to, schools they have gone to, foreign degrees conferred upon them, companies they work for etc. When desis check facebook/orkut profiles online, they most certainly check for all the above cues along with their tastes in music and film. A degree from an ivy league school, an americanized accent, a little goatee, a liking for Coldplay or Death cab for Cutie are sure to get you placed you up there.
But to get yourself placed in a totally uber category, you should be dating/married to a white person or at the minimum having lunch/coffee with a non desi.
