SINGAPORE - When he was seven years old, his mother ran away from home and Mr Rayson Choo and his father, a security guard, spent weeks scouring the island hoping to find her.
"My father was frantic, and we even made a police report," said Mr Choo, 28. "I wasn't sure what was going on. I only knew that my mum wasn't coming home. I was crying, upset and afraid."
