A Nashville mother posted a heartwarming thank-you note on Facebook to an Apple employee who went above and beyond to help her son who has special needs.

LynnMarie Rink, 50, and her nine-year-old son, James, stopped at the Apple store in the Green Hills mall on their way home.

James wasn't feeling well that day and as soon as they got off the elevator he bolted and hit a wall.

James wasn't feeling well on the day his mother, LynnMarie Rink, took him to get an iPad that he uses to communicate, but Andrew Wall (right) an Apple employee sat on the floor with them and helped James with his new iPad

'The sound was so horrifying and everybody turned to look. I stood there frozen and thought for sure he was going to be covered with blood,' said Rink.

'James has a high tolerance for pain and when I got to him he just poked out his lip and a few tears fell.'

Rink and James sat on the floor and were immediately met by 23-year-old Apple employee, Andrew Wall.

'Are you okay?' he asked. 'What can I do for you?'

Rink asked Wall if they could finish shopping for an iPad and do the transaction on the floor. She wanted to keep her son there to prevent upsetting him further.

James, who usually doesn't like interaction with other people, gave Wall a fist bump after he helped them complete the transaction and setup the iPad on the floor of the Apple store

'It was such a simple act. He just sat down and that's all that James and I needed,' Rink said.

She said James usually doesn't like interaction with other people, but he can sense their spirits and when she asked him to give Wall a fist bump, he did.

'Nobody gets how powerful this moment was,' Rink added.

Rink has received hundreds of emails from special needs parents saying they now have faith in humanity along with others who were willing to help identify Wall.

The Facebook post has more than 1.3 million page views and it has been shared more than 20,000 times.

Rink said James came into this world to teach everybody how to love unconditionally and he has changed her life for the best

'Just meet me where I am and he did just that,' said Rink. Wall even showed James how to use his new iPad.

Wall, a Belmont psychology grad, wrote to Rink:

'I began working at Apple in hopes of having fulfilling moments like this. My hopes are to work within the realm of youth counseling. Thanks again for making my day!'

WRAP YOUR HEART AROUND IT Wrap Your Heart Around It by LynnMarie Rink Wrap Your Heart Around It is Rink's memoir that was inspired by her son, James, who has changed her life for the best. After spending years trying to learn how to cope with the challenges of raising a child with special needs, Rink learned that her son came into the world to teach people how to love unconditionally. Rink discusses how James has saved her life everyday and despite years of depression she found faith. Advertisement

Rink – who has written and performed a one-woman show about raising a child with special needs – said she is very grateful to Wall for how he handled the situation, as it has not been easy for her to cope with having a child with special needs.

When Rink was three months pregnant with James, she found out that he would have Down Syndrome.

She and her husband had waited close to 20 years before having children.

'I told my self repeatedly that "I didn't want this child and you're going to be the death of me."

'But I heard this small voice that told me "this child will save you from yourself"'.

Rink said she spent four years dealing with depression and used therapy to get her through.

When James turned six he was diagnosed with autism and things got harder everyday for her and her husband.

'I just couldn't wrap my head around it, but then I realized that I needed to wrap my heart around it instead.

'James came into this world to teach everybody how to love unconditionally and to change people's hearts.'

Rink, who said James saves her everyday, wrote a memoir about learning to love the life you have, which discusses the difficulties around raising a child with special needs.
