Sometimes it happens at the train station, sometimes on the street. Sophie English can see the question in their eyes, before they ask it.
“Excuse me, do you mind if I ask where you come from?”
Some strangers think she is Chinese, Maori or even native American. The truth is, Sophie English was born in Saigon during the Vietnam war and adopted by an Australian family.
"I am Australian as they come, you know? Frickin' I like Vegemite, meat pies and I can swear like a trooper.
"I feel totally privileged to be Australian. I don't feel anything else but Australian, but ... there's still that part of me that is Vietnamese."
Sophie is returning to Vietnam to make peace with her past, as the nation commemorates 40 years since the end of the war.
She was only 10 months old when she was flown out to Australia in 1969.
"I've lost my whole culture. I have lost my whole identity, my language, my food. You know, I'm 46 years of age, Vietnam back then would have been completely different to now."
Sophie has very little information about her biological family or why she was adopted. Like so many others who were sent out of Vietnam during the chaos, the paperwork was either lost or has turned out to be wrong.
As she walks the streets of Ho Chi Minh City, she could be walking past her mother at anytime and not know it.
She is torn between maintaining hope and trying to extinguish it, so she can get on with her life.
