Kavita Kaushik: Sakshi Tanwar is both my 4 am and 4 pm friend. She's more like a sister. We discuss everything under the sun, including what we eat for breakfast, lunch and dinner. We have been there for each other in crisis and happiness. We are poles apart as personalities, but what has got together, is the fact that we are identical as souls. Guess you can call us soul sisters. The catch is, that even if I wake her up at 2 am, I'll have to pick her up because she can't drive.
