The first reunions of North and South Koreans in more than three years came too late for 90-year-old Seo Jeong-suk. She died in South Korea just 15 days ago.
So the daughter she grew old with, Kim Yong-ja, could not reintroduce her to the one she had not seen in more than 60 years. Kim, 68, could only sob and hand her long-lost sister a framed photograph of Seo, according to South Korean media pool reports.
Kim Yong Sil clasped the photo to her chest and said: "It's mum's photo."
Dozens of elderly Koreans wept and embraced in a rush of words and emotion on Thursday at North Korea's Diamond Mountain resort, in a rare period of detente between two bitter rivals that were once a single country. The reunions were all the more poignant because the participants will part again in a few days, likely forever.
South Korean TV showed old women in brightly coloured traditional hanbok dresses talking and hugging, families trading photographs of relatives who couldn't attend or had died. Two men in suits and ties wiped away tears, grasped each other by the necks and pressed their foreheads together as cameras flashed. One old man was wheeled in on a stretcher, his head propped on a pillow, a blue blanket wrapped tightly around him.
Ageing and illness made some reunions bittersweet.
"Sister, why can't you hear me?" North Korean Ri Jong Sil, 84, asked 87-year-old Lee Young-sil, who has difficulty recognising people because of Alzheimer's disease, according to pool reports.
Tears flowed down Ri's deeply wrinkled face as Lee's daughter began sobbing, telling her mother: "Mum, it's my aunt. It's my aunt. She's your sister."
The difference in the sisters' family name is a product of the Korean Peninsula's division: It's basically the same family name but each country uses different spelling rules in both Korean and English.
Ri Chol Ho, 77, from North Korea, used a piece of paper to communicate with his 81-year-old brother from South Korea, Lee Myeong-ho, who has a hearing problem.
"Mother used to tell me that you would return home and buy me a pair of rubber shoes," Ri wrote on the paper that he passed to his brother, according to the pool reports.
About 80 South Koreans travelled through falling snow with their families to meet children, brothers, sisters, spouses and other relatives. Seoul had said about 180 North Koreans were expected.
The meetings are a vivid reminder that despite 60 years of animosity, misunderstanding, threats and occasional artillery exchanges, the world's most heavily armed border divides a single people.
Millions were separated from loved ones by the tumult and bloodshed of the three-year war that ended in 1953, but few have been reunited. During a previous period of inter-Korean rapprochement, about 22,000 Koreans had brief reunions - 18,000 in person and the others by video. None got a second chance to reunite, Seoul says.
Thursday's reunions were arranged after impoverished North Korea began calling recently for better ties with South Korea, in what outside analysts say is an attempt to win badly needed foreign investment and aid. The North, however, sent mixed signals by threatening to scrap the reunions to protest annual military drills between Seoul and Washington set to start Monday.
Many in Seoul are also wary after last year's springtime threats from North Korea of nuclear strikes against Seoul and Washington. North Korea in recent years has conducted nuclear and missile tests, and is blamed for attacks in 2010 that killed 50 South Koreans.
Last week, North Korea decided to honour its earlier promise to allow the reunions after South Korea agreed to North Korea's proposal that the rivals stop insulting each other. In South Korea, there are still worries that the reunions might be disrupted because of the impending military drills.
The reunions are broken into two parts. Thursday's reunions end Saturday. A second group of about 360 South Koreans plans to visit the mountain resort Sunday to meet with 88 elderly North Koreans. Those reunions end Tuesday.
Both governments ban their citizens from visiting each other or even exchanging letters, phone calls and emails.
In Pyongyang, North Korea's capital, many people had heard of the plan to hold the reunions on the television news or other state media. "I desperately hope for reunification. We are of the same blood and getting these families together will help national reunification," said 63-year old Jang Hye Sun.
The two Koreas have been in a near-constant standoff since an armistice ended the Korean War. It hasn't been replaced with a peace treaty, leaving the peninsula still technically in a state of war. About 28,000 US troops are stationed in South Korea to help deter aggression from North Korea.
In 2000, South Korea created a computerised lottery system for South Koreans hoping for reunions, and since then nearly 130,000 people, most in their 70s or older, have entered. Only about 70,000 are still alive. It's not known how North Korea selects people who attend reunions. South Korean media reported that the North usually chooses those loyal to its authoritarian government.
According to pool reports, it was only through the application process that 93-year-old Kang Neung-hwan even realised that he had left a son behind when he left North Korea during the war. Kang Jong Kuk, now 64, had been in his mother's womb at the time, and his father had not been aware that she was pregnant.
And when they finally met Thursday, the elder Kang could not resist a little gentle teasing.
"You look old," he told his son. "Come give me a hug."
