1) Professional thief or street rat ala Aladdin (who I know isn't Indian, but just to give an idea) in pre-colonial India -- what caste, if any, would they have been in? I can find oodles of info on the caste system through the ages, but all seem to refer to your general traders/farmers/merchants/rulers/soldier
2) What's the difference between a bindi and a tilaka? Same thing, different word for different countries? Wiki and Indian culture sites kept screaming at me "THESE ARE NOT THE SAME" but never told me how they weren't the same. Bindi appeared to refer to the jewel in the middle of the forehead, whereas tilaka was a red dot between the eyes--completely wrong, interchangeable?
