For 26 years, the kids at Central Elementary School in Pollock, Texas, have known Miss Bettie Turner simply as "Granny."
Granny never had children of her own, so she's devoted her life to volunteering at the local elementary school, acting as a role model for several generations.
On her 100th birthday, Granny celebrated the milestone with the people she calls her "second family," the children at Central Elementary.
"I thank God I'm still alive and able to get around," Granny said.
"She helped us learn a lot," first grader Cullen Merrell said. "She tells me what to do when I mess up."
"Whenever she walks in, they're all, 'Hey Granny. Good morning, Granny,'" teacher Jamie Solly said. "Everybody wants to hug her and she always has a hug for everyone."
"I love these children," Granny said. "They all obey, so I like that."
More than 600 pre-kindergarten to fifth grade students filed through to wish their "Granny" a happy birthday. Miss Turner said volunteering is what keeps her young.
