LAGUNA BEACH, Calif. – Laguna Hills High School wants girls to know they’re special.

So when they came to school last Thursday, the mirrors in the girl’s bathrooms were gone, replaced with signs of affirmation like “You’re doing better than you think!” and “You are extraordinary.”

Others read “smile” and “keep your head up,” as well as “You are enough,” “You are beautiful,” “Positivity can change your life,” and others.

The change came after 17-year-old student Sabrina Astle, a member of the campus Kindness Club, approached school officials with her idea for the school’s “What if … Week” last week. The theme for Thursday was “What if we showed more love?” ABC News reports.

“This is why I started making the posters in the first place,” Astle told the news site.

“I felt this would be a good time to hang the signs,” she said. “I put the signs in the bathroom the night before so students would see them throughout the day.”

“It made their day,” Astle said.

Laguna Hills activity director Chelsea Maxwell said Astle has channeled her energy this semester into promoting positivity on campus, and student organizers who helped with the project last week were “overwhelmed” with positive feedback.

“Our hope is that the signs remind our girls to focus on everything they are – smart, loved, important – and so much more,” Maxwell told Fox 5.

Astle said the response from her classmates was more than she expected.

“I didn’t think I was doing anything that would impact anyone,” she said. “I thought it may brighten their day or lift their confidence before their next class, but I didn’t think it would make this large of an impact.”

The whole project is aimed at highlighting equality and compassion for others, she said.

“The signs have helped people remember that everyone is beautiful, everyone is important, everyone is good enough and everyone should be treated equally,” Astle said. “I did this because I am passionate about the fact that everyone is important and everyone needs to be cared for.”

School officials ultimately decided to keep the signs in place for now, and a school visitor discovered them over the weekend and posted photos to the feminist Facebook group Pantsuit Nation, the New York Daily News reports.

That post, by Shannen McKinney Lob, quickly exploded to 52,000 likes and well over 1,000 comments over a couple of days.

“I walked into the girls bathroom at a local high school over the weekend and was so amazed and overjoyed at what I saw,” McKinney Lob wrote. “No mirrors just affirmations!”
