The concept of raakhi brother tickles me silly. Raksha bandan wasn't particularly a custom around us growing up. Plus largely liberal parents who didn't mind boys - platonic friends walking in and out; girls in the case of my brother. So we had friends of the opposite gender all the time. All of a sudden this craze caught up and many girls and boys whose parents were restrictive went on an over drive. Any boy one was unrelated to but whom they wanted to hang out with seemed to become raakhi brother. Any good natured ribbing and a sanctimonious, he's my raakhi brother man would be the rebuke. Funnier still is the fact that I know of several lovely couples who started out this way and went on to get married! The things kids had to do to find their own soulmate!!
One's rotis should always be round. There are only two career options in India: Doctor / Engineer. A government job is always treated better than private. Even if one works with the government, one's kids will go to a top-notch private school.
Hair Oil - coming to work or other places with thick coconut oil in hair. Many of us grew up with hair always oiled, but, move with the times, kick that habit. Hair oil is fine as a pre-hair-wash ritual in the privacy of your home. And if you have to keep your hair oiled all the time, at least pick a lighter Brahmi aamla kesh tel kind, not good old Parachute. Call me sexist, but it looks even more appalling on men. Use modern options like gel, cream, and what have you. Sweaty people - yes, we come from a tropical land. But, when working in an air-conditioned office, and in a semi-formal or formal dress protocol, please do something about sweaty under-arms and etc. Especially, women... you want to wear sarees.. do.. but, do something yaa... Smile! Why do Indians nod or smile at non-Indians, but ignore an Indian in same scenario? : ) .
I always got a "Are you crazy?" look from Indians when I smiled at them. There are (very) few who reciprocate.
Not sure if this part of all Indian families. Even after guests are inside the house and seated, each and everyone should be welcomed individually. Like it or not, a friendly or respectful "Aayiye" or "Vaanga" should be uttered.
Eating with hands. If you ask for spoon you are considered a show-off. Close relatives would even tick you off with why God gave you hands?
A custom in my friends family (they follow same here in UK) - Men should eat first and women later. When we go to her place for lunch / dinner on their invitation, eventhough I am hungry, men has to eat first, women has to wait for their turn
Because only Indians are your competitors in the next GC being filed, or eyeing the great house in a good school district or want the last pair of pants on clearance in Kohls during 30% off? Noticed this phenomenon in every city in US I've ever been to....
