Many times, friends bond over something they have in common. They may work together, go to school together or be involved in the same activities. They might both like the same type of movies, hobbies or food. However, sometimes it’s the differences people have that actually make them the best of friends.

When Chris Salvatore was 31 years old, he lived in an apartment complex in West Hollywood, California. His next door neighbor was an 89-year-old woman named Norma Cook. It might seem unlikely that they would become friends, but they did.

Chris posted a series of videos on Facebook where he explained how their friendship started. In the first video, he explained that Norma had Leukemia and didn’t have any family around. One day she said “hi” to Chris through her apartment window. , He asked if he could come inside. She opened the door, and they bonded over sparkling wine and sparkling conversation.

In his second video in the series #myneighbornorma, Chris shared that he and Norma started to go on errands together, such as going to the grocery store. They also enjoyed fun activities together like watching movies or having a BBQ in their apartment courtyard.

In the third video, Chris described Norma as a grandmother figure in his life. Norma didn’t have any children or grandchildren, so he was like a grandson to him.

Unfortunately, Norma’s health was declining. She was frail and fell in her apartment. This happened more than once, and eventually, the doctors at the hospital decided that it wasn’t safe for her to live by herself anymore.

Fortunately, Norma had Chris for a friend, and he was not about to give up on getting Norma home.

In the forth and final video in the series, Chris shared that he started a GoFundMe to raise money to prevent Norma from being sent to a county run nursing facility. He was able to raise enough to pay for in-home care so that Norma could return to her apartment.

Chris didn’t end up sharing a part 5 of the video series, but the story does not end there. Eventually the money ran out, but instead of sending Norma to live in a nursing facility for her final days, Chris invited Norma to move into his apartment where he could watch over her. Norma agreed.

Chris spoke to TODAY about having Norma move into his apartment, and he claims that there was really no other option. He said, “The only other option was for her to go into a facility. I just couldn’t do that to someone who is like my own grandmother.”

Norma is no longer with us, but Chris will never forget the impact her friendship had on his life.
