You look Bengali!

The world is a weird place. I'm sure I was meant to born in some other planet. Why I find the world weird is a complicated question with many different answers but one of them is "What does 'looking like Bengali' mean?". Honestly, since the time I learnt to speak, I've been hearing " You look Bengali" or "Are you Bengali?". I may walk into a place where no one knows me and someone will surely come up with one of these questions. And when I reply in affirmative, they will inevitably clap their hands together and say " I knew it!". Ironically, my Bengali ancestry from my parents is never recognised. When people realise that my mother is Bengali, they are very surprised.
 So I decided to look into it to find an answer. Turns out Bengalis are known for their big eyes. Oh yes, I do have big eyes but so do about 100 million other people, if not more. So what makes me so distinctly Bengali? So I asked a friend of mine. She told me that most Bengalis are talkative. Really? Yes I can be very talkative but it depends on the person I'm talking to. Then later on, she came up with another theory that Bengali people pout a lot. Okay, I probably laughed for an hour and spent about another hour  checking in the mirror and asking everybody around me if I really did pout. I don't. Really, I checked.

After being thoroughly confused for days I decided to Google about it. Not a good idea. All I saw were a bunches of baseless stereotypes (and I hate stereotypes) and a gazillion pictures of Bipasha Basu and Rani Mukherjee in  white saris with red border. I, for one, do not wear saris and don't look like Bipasha Basu or Rani Mukherjee. Really, I checked, again. So, all I can ever do is just ponder over this and never find an answer, unless you can help me.....What makes someone look Bengali???
 Waiting for some answer. See Ya'll. Bye.
