Adonai Gutierrez walked into his Maxwell Elementary School classroom this week knowing that he had received something no one else had before him: two birthday parties.

The 7-year-old got to celebrate his birthday twice thanks to a social media campaign.

But while Adonai’s first party was something better forgotten, his second should be one to remember.

The youngster had what was perhaps one of the worst things to happen to a child on April 22 after his parents put together a birthday party for friends and family at Woodside Park.

No one came. The party was a disaster. A full birthday cake went home. So, too, did the pinata.

Adonai was downcast to say the least, asking his parents and grandmother why no one came?

That all changed on Sunday, when more than 200 people sang “Happy Birthday” to young Adonai at a communitywide party held in Jack Slaven Park.

Along with stacks of pizza — which Adonai said is one of his favorite foods — there was loads of cake, dozens and dozens of cupcakes, games, bounce houses and plenty of other children all willing to spend time in play.

Adonai, with neatly slicked-back black hair, could only look on with a certain element of wonder and confusion as he was driven to the park in a lime-green roadster and walked up to the raucous crowd of well-wishers.

The entire event was a surprise, despite the weeklong online announcements.

According to grandmother Ofelia Mercado, Adonai’s mother, Maria Lopez, put together the earlier party at Woodside Park. The invitations went out in plenty of time. But when 2 p.m., April 22, rolled around, no one came except for immediate family. Then the family waited, and waited, and waited some more

At 9 p.m., a disappointed Adonai went home wondering, Mercado said, where everyone was and why should he have a birthday party ever again?

But fate intervened when family members, friends and others started posting the story through Facebook and other social media outlets.

That led to a mention on several Sacramento area television stations, and as one of the organizers, Ryan Boone, explained, the community party started growing.

Boone didn’t know Adonai until Sunday, but he worked with others to make sure the youngster had a birthday to remember.

The city of Woodland also helped out. After Community Services Department staff heard about the party, the city waved the $20 an hour fee to use an area of the park.

Adonai — who was soon sporting a specially made Tee-shirt with his name on it — seemed flustered for a time as he was hugged by parents and greeted by other children. But he was soon running after his peers, squirt gun in one hand and a bubble wand in the other.

Adonai’s mother, Maria, was equally grateful to the community.

“I think this is great,” she said, looking around as dozens of people celebrated. “There’s a lot of love here. And I’m super grateful.”
