Two women who always had a lot in common recently discovered that they were actually biological sisters.
Diane DiProspero Cook took a class taught by Karen Cometa-Zempel at Bryant and Stratton College in 1985.
Neither had any idea they were related.
“We lived parallel lives,” DiProspero Cook told ABC News. “We think alike, we have the same mannerisms.”
Both were adopted as children and grew up just 20 miles apart in New York.
The sisters were raised in close Italian families and went to Catholic schools.
Last month, they learned they were sisters after receiving a letter from the New York State Adoption registry with each other’s names.
Both had reached out separately and to find out about their medical histories.
"I couldn't believe it," DiProspero Cook told WHAM. "I immediately knew who she was."
"When she called me, she said, 'I know you!' and I said, 'Diane, what do you mean, you know me?'" Cometa-Zempel said.
The two sisters have been making up for lost time.
In addition to a similar upbringing, the sisters discovered they both are left-handed, love shopping and have outgoing personalities.
“The more we talk, the more we find we have in common,” Cometa-Zempel said.
