Boss, please don't quote your own personal experience.
Though I am from Karnataka, they understand what Karnataka is. So do they understand Andhra and Kerala as well.
People of Tamil Nadu are not dumb not to know the 4 southern states. Infact, in South, we do study the geography of India in much greater detail than other states. Hence, we are much aware of the geography. OK.
If you speak Hindi, they may perceive you as a North Indian. But if you tell them, where are you from, they will know.
Unlike some uni-dimensional Maharashtrians who feel all from South India are Madarasis and MUST eat Idli, Dosa and Sambar for breakfast, lunch and dinner.
