For 75 years, Morris Sana had thought that his cousin and best friend Simon Mairowitz had passed away during the Holocaust. That’s what made it all the more heartwarming last week when 87-year-old Sana and 85-year-old Mairowitz cried tears of joy when they were reunited in Israel.

The cousins were best friends before the Nazis invaded Romania in 1940, forcing both of their respective families to flee the country separately. After they were separated, both Sana and Mairowitz grew up believing that the other died in a concentration camp in Europe during World War II. It was only recently that Sana’s niece and daughter connected with relatives on Facebook, leading to Sana and Mairowitz’s touching reunion in Tel Aviv.

A heartwarming viral video shows Sana and Mairowitz overcomed with emotion as they walked towards each other, holding out their arms and hugged.

“Good to see you,” Sana, who lives in Ra’anana, Israel, tells his cousin. Mairowitz responds, “Good to see you too after all these years. Seventy-five years you waited.”

“I know it’s a long time,” continues Mairowitz, who now lives in the United Kingdom, as both men cry. “We’ve got each other now. And we can see each other.”

Sana later tells Mairowitz that he thought of him often over the years.

“I imagine you when you were a little boy,” he says.

“You remember, don’t you?” Mairowitz responds. “I can’t remember that.”

“I’m glad to see you,” Sana repeats.

“So am I,” replies Mairowitz. “Very, very glad.”
