Matt Cobrink, 53, hasn't traveled much, especially since his mother passed away.
But he recently had the opportunity to fly from California to New York to meet his favorite baseball player, Aaron Judge of the New York Yankees.
Although he had a great time in New York with his sister Janet, the absence of his father's daily presence made the heart grow fonder as evidenced in a viral video filmed by Matt's sister.
Matt's sister, Marcy Cobrink Mayer, 56, knew how emotional her brother would be at the airport upon his return to California. When he flew home on August 12, Marcy and their father, Malcolm Cobrink, 88, were there to welcome him home at LAX and she had her smartphone at the ready to capture the emotional reunion.
"Homecoming doesn't get better than this," Mayer wrote on her Facebook post with the video. "I think my brother missed my father after 5 days in NYC with my sister."
Marcy shared with PEOPLE about the special bond between father and son.
"I knew that my brother and my father are so closely attached, and I knew that after five days my brother was going to really be missing my father."
"They're never separated for five days!"

In the video, Matt hurried down the escalator after spotting his family and immediately made his way over to Malcolm with arms open wide.
"I don't think you missed him, am I right?" Marcy teased her younger brother, while filming.
Marcy's video showing Matt hugging and smothering his loving father with kisses went viral with over 18 million views.
Many people left comments about being brought to tears.

According to Marcy, Matt is very affectionate and she wasn't surprised about his emotional response at the airport.
"I expect that kind of reaction from him," she said of her brother.
"Sometimes I won't see him for a few days, and then I'll go to his house or my dad will bring him over here, and he will kiss me like 20 times. He's just really very loving and happy to see everybody!"

Marcy shared how her father and brother's tight relationship had a huge impact on other parents of children with Down Syndrome.
"People all over the world were sending me pictures of their children with Down Syndrome, telling me that it made them cry, that they're so happy to see such a long, loving relationship between my father and my brother."
"It gives them hope for their children or they have a cousin who has Down Syndrome. And that it's so nice to see something that's happy instead of things that are negative."
It looks like the Cobrinks accomplished their mission of spreading joy on the internet.
"We just want to share the love. We want to let people know that it's really not Down Syndrome, we call it 'Up Syndrome,' because my brother has brought so much love into everybody's life that he comes in contact with."
"It's just really remarkable."
