STOCKHOLM: Jyothi Svahn calls this little-frequented hill near the Stockholm international airport ‘The Rock’. It is where she feels “safe enough” to let her tears flow freely without anyone judging.

“(People) always question my tears and my memory of her,” said the university student about the half-remembered fragments of a woman’s image she believes to be her mother. Watching plane after plane barreling down the runway and shooting off into the sky, she added: “One day, that will be me going to India to see if I can find my mother.”

Ms Svahn was only four years old when her birth mother disappeared on her and her sister Gayathri, who is a year younger. The memory of being abandoned at a playground in Bangalore is a traumatic one that has never stopped haunting her.

“She just turned her back on me. She did not look back when I screamed. She just left,” said Ms Svahn in between sobs. “Even though I am 27, I still cry about it.”

The Svahn sisters ended up in Ashraya Children’s Home – an adoption agency based in Bangalore, India – in 1993. A year later, their Swedish parents adopted them through Adoptionscentrum, one of the world’s biggest adoption agencies that has handled more than 25,000 cases of inter-country adoption.
