Kids say and do stupid things. But a daughter’s Facebook post may be the worst of all time. According to the Miami Herald, Patrick Snay, 69, was the headmaster at Gulliver Preparatory School in Miami for several years. In 2010, the school did not renew his contact. Snay sued his former employer for age discrimination and won a settlement of $80,000. The agreement contained a standard confidentiality clause, prohibiting Snay from talking about the case.

However, Snay’s daughter, Dana, now at Boston College, couldn’t resist bragging about the case on Facebook. “Mama and Papa Shay won the case against Gulliver,” she wrote. “Gulliver is now officially paying for my vacation to Europe this summer. SUCK IT.”

Dana has 1,200 Facebook friends, many of whom are current and former Gulliver students. News of the post made its way back to the school’s lawyers, who appealed the verdict. The Court tossed out the $80,000 settlement earlier this week. If Snay’s daughter had been discreet, the court would not have discovered the breach of the confidentiality clause.
