Sam Cornelius is from India, and works in the U.S. tech sector. Sometimes when he meets another Indian at his company, they ask him questions that seem innocent enough on the surface, like, "Where is your family from?" Or, "Are you vegetarian?" Sometimes they might even suggest going for a swim. But, Sam says, these questions can feel like a dangerous trap. Coming from a fellow Indian, they're often clever attempts to find out something very specific: his caste.
