COCOA, Fla. (CBS Tampa) — An eighth-grade girl was told by school officials that she needed to change her t-shirt that promoted abstinence.

WOFL-TV reports that Clearlake Middle School forced 15-year-old Summer Schreiner to change out of her shirt that read “Don’t Drink & Park: Accidents Cause Kids” which she got at the Silver Ring Thing, a Christian youth conference.

“I was pretty upset. I thought it was silly,” Schreiner told WOFL. “It’s not like I was wearing a curse word or something that was promoting violence.”

Angela Hogan, Summer’s mother, called the experience “humiliating” for her daughter.

“They actually had her take off the shirt and put on a T-shirt the school issues for inappropriate dress. And the shirt they had her put on says, ‘Tomorrow I will dress for success,’” Hogan said.

The school stands by its decision to make Schreiner remove the shirt, saying it violated school policy.

“This is not a situation of whether or not the district agrees or disagrees with sexual abstinence among teenagers,” Michele Irwin, director of communications for Brevard Public Schools district, told WOFL. “It’s about the fact there is sexual innuendo on the shirt, and so we believe it violated our dress code policy.”

The Silver Ring Thing program – which started in 1995 – promotes purity and abstinence until marriage. The program has hosted nearly 1,000 events around the country and has given out more than 200,000 rings to students.
