I looked at her and waved. She waved back. I could see in her eyes the pain I had suffered. I also saw the tear-stained cheek, just like mine. That ray of hope in her expressions.. It seemed so familiar. It almost felt like our struggle was exactly the same. Who was she? Ah, realisation struck. She was my best friend, the girl who had been with me through the worst. The person who made sure that I don’t give up, that we keep going. We stood there staring and smiling at each other for a long time, like long-lost sisters. Then, when we tried hugging, we couldn’t. There was something separating us, something resembling a glass wall.. Who was she? She was me.
