Some Do's for India (New Dehli)

Be silent and listen.
To whom? Do you never speak? Find out what the parameters are. Women? Men?
Respond to questions concerning status, money, and family. What kinds of questions? We need to get details. Are there no inappropriate questions about those aspects of your life?

What kinds of responses are appropriate? Does relative power status matter?
Do dress modestly. Define modest in terms of concrete clothing and practices.
Eat with your hands, but don't take food from serving dishes with your hands (use a utensil). Everywhere? Restaurants? Cafeterias?
Keep your clothes clean and ironed and maintain very good hygiene. Clean is relative. Lots of Europeans wear the same skirt day after day, horrifying their squeaky clean shower and laundry obsessed American companions.
Apologize for inadvertent touching. Where? On the train? In a shop? On the street, in someone's home? What kind of touching? Paint us a picture (and by that I mean, get your informant to paint you a picture).
Exercise discretion when discussing poverty and the caste system. When might it be appropriate to raise this issue? You are likely to find that people bristle
Understand that family is very important. This is way too vague to be useful. In what culture would they Not say that family is important. We need illustrations of the kinds of practices in daily life, choices and decisions people make that show the importance of family to work, personal pursuits, religion, yada yada.
Try to blend in and acclimate. ??? That is the whole idea, yes, but it's kind of like saying, "Be a good Indian." You have no idea what that means. You need exact practices that will cause "blending in and acclimating" to occur.
Mind your temper. Again, is there any culture where this would not be advised? What we need to know is what makes people feel you have "lost" your temper? Voice, facial expressions, words or phrases, actions. . .
Ask people to clarify if something is unclear. Who when where why how? EVERY time you're not sure what someone means? Because you will likely tire your hosts in about 15 minutes if you have to ask about Everything that is Unclear.

Accept unspoken apologies. Ok, what is an unspoken apology?? How do you know one has occurred? How do you demonstrate your acceptance of it? What kinds of transgressions are to be taken lightly.?
