Me and my twin always certain that we are different. We eat breakfast differently, we live in entire different city and not forget to mention, different caregiver. I, Kim Sunna live with an old grumpy tried to be optimist father. My twin, Kim Sunni live with the modern trendy 'I hate tradition' mother. We swipe each other place and who knows we are not that different, we are twin after all. And possibly we could know the side of us that we are too afraid to show because we are too certain of who we are or actually what people want we to be.
