When seventeen-year-old Mackenna came home, she immediately noticed her father doing something strange. He was sitting in a chair just outside of Mackenna’s mother’s room and had the door slightly ajar. As it turned out, Mackenna’s mom, Marci Newman, had been diagnosed with thyroid cancer and had been having a tough time with her radiation treatments, so her husband decided to dedicate himself to her treatment and recovery by posting himself outside of her door in case she needed anything at a moment’s notice.

Part of Marci’s treatment requirement was that she remain in isolation. Although she had to be apart from her family while undergoing her cancer radiation treatment, her husband, Jon Newman, refused to let that stop him from doing whatever he could to show his wife that he was there for her no matter what.

Mackenna snapped a picture of her father from behind. She loved seeing her father sitting in front of her mother’s room because it meant that he loved her and was willing to sacrifice his comfort and time for her recovery and wellbeing. Since she found her father’s dedication so inspiring, Mackenna shared the picture of her father on social media, where it quickly went viral.

“My mom has to stay in her room in isolation for her cancer radiation, so my dad set up a desk at her door to keep her company, and I’m crying,” Mackenna wrote on Twitter.

Within a day or so, Mackenna’s tweet went viral and received as many as 71,000 retweets and more than 172,000 likes. People on social media were eager to share in the loving moment and let their thoughts be known in the comments.

“Amazing…may she heal soon. My heart goes out to you and your family,” one person wrote. “Stay strong. You have an amazing Dad.”

“Kenna, I’m a #ThyCa survivor & a nurse. This is the sweetest!” wrote another user. “Loads of love [and] luck to your mom! Please let me know if I can help.”

“Beautiful! True, beautiful, [meaningful] love,” wrote one Twitter user. “All the best to your mom.”

“My heart is melting. Tell your mom I’m praying for her [and] your Fam,” added another. “Your parents are amazing. Praying for a positive outcome for you all!”

“I am a little late discovering this inspiring tweet, thinking of you and your family. Your parents are amazing,” wrote another. “Your dad. Incredible!”

Mackenna was overjoyed that her picture inspired so many people. She spoke to BuzzFeed News about her dedicated dad.

“The amount of love I’ve received is crazy, and I didn’t expect any of it, but I’m so grateful,” Mackenna told BuzzFeed News. “I just thought it was sweet because they are so in love.”

Meanwhile, mom knows she snagged a good husband.

“Jon goes to every doctor’s appointment, every blood test, every surgery, every radiation,” Marci said. “And, as you can see, if he can’t be by my side, he is as close as he can get!”
