She is grieving for the midwife who brought her into the world and became her mother.
Ms Pearly Chin's birth mother, who had wanted a boy, had rejected her when she was born in 1972.
The woman even asked Madam Chin Siat Keow to sell the baby, but the midwife did not have the heart to do it and adopted the child instead.
So when retired nurse Chin, 81, was hit by a tipper truck on Saturday and died from her injuries, Ms Chin, 41, felt the loss of a dear mother.
Madam Chin was hit near the junction of Henderson Road and Jalan Bukit Merah at about 12.40pm that day.
She was taken to the Singapore General Hospital, where she later died.
Ms Chin, a secretary, recounted the story of how she ended up with Madam Chin.
"She (the birth mum) asked Mummy if she could help sell me. Mummy had done many deliveries, but somehow, she felt a bond (with me)."
Ms Chin said Madam Chin, who was single, then went home, discussed it with her family and took her back on the ninth day, giving her birth mother a $2,000 token.
Ms Chin lived with Madam Chin and Madam Chin's sister, Ms Shirley Chin, 63, who is single, in a Haji Lane shophouse in Kampong Glam.
To "balance things out," she called Madam Chin "Mummy" and her sister "Daddy".
And Mummy, said Ms Chin, was very strict. "I couldn't watch TV and eat at the same time. Even now, when I'm alone, I eat at the dining table.
