Pre script : This is an actual conversation with a colleague :)
ME: Are you a Mallu ?
HE: No, I am not a Mallu! (emphatically)
ME: But you speak Malayalam.
HE: Just because I spent so many years with 2 people who speak Malayalam doesn't mean I am a Mallu. I was born and brought up in Chattisgarh ( reiterates)
ME: And who are those two people?
He: My parents.
