Happy Birthday Colin

Over 1.6 million people have joined a Facebook birthday party created by a Michigan woman for her son, who is unable to make friends.

Jennifer Cunningham created the page after her son Colin, who suffers from an autism-like condition as well as sensory processing disorder.

Cunningham said she was moved to create the page when her son told her he did not want a birthday party because he did not have any friends to invite.

Cunningham created the Happy Birthday Colin page with the message: "I am Colin's mom, I created this page for my amazing, wonderful, challenging son who is about to turn 11 on March 9th.

"Because of Colin's disabilities, social skills are not easy for him, and he often acts out in school, and the other kids don't like him. So when I asked him if he wanted a party for his birthday, he said there wasn't a point because he has no friends.

"He eats lunch alone in the office everyday because no one will let him sit with them, and rather than force someone to be unhappy with his presence, he sits alone in the office.

"So I thought, if I could create a page where people could send him positive thoughts and encouraging words, that would be better than any birthday party. Please join me in making my very original son feel special on his day."

Cunningham also stated on the site that it is getting more and more difficult to keep the page a secret from her son. She is hoping it won't spoil his birthday surprise, a moment she plans to record on video.

"Several kids at school told him they saw him on the news, and he overheard a teacher saying to another teacher that she saw him on Facebook," she wrote. "He doesn't know about this page yet."
