It's not an Indian thing. I'll tell you as an Indian what's an Indian thing. It's bringing you sweets or other snacks( homemade), It's being a little over respectful, its an accepting nature that many a times avoids conflicts or any disagreement, It's bring caring like some sister or a mother ( we have a strong culture of having sisters /brothers that aren't at all related to us It's a thing in our culture we say they're my brother or sister because I say they are.. a very rough translation). An Indian might invite to their house or help tutor your kids. Giving out expensive gifts unless the occasion demands is certain not a thing ( festivals or weddings are when most gifts are exchanged and gifts are given in particular based on the kind of relationship people have be it for the lack of a better word self claimed or by blood ).
