"It's unacceptable and we're on it," he wrote.
While that might be enough for reasonable adults, it was not enough for Semma, who had slipped and fallen in the icy lot that morning.

Young Leo was rewarded for his insouciance with a three-day suspension, and it seemed the saga was over. Leo'd had his say, the Gut-man his retort. But Leo was just biding his time until his graduation could be made official.
Earlier this week, the 17-year-old posted a photo of his suspension notice to Twitter, along with the original tweets. His brag quickly spread beyond Michigan to the wider internet, where a superintendent's authority is helpless against the might of tens of thousands of retweets.
According to BuzzFeed, Gutman has blocked Leo on Twitter, but others are now trolling the superintendent by tweeting "get your ass out here at 5:30 sharp boi" at him.

Congratulations on your graduation, Leo. Here's another news article to put on your future LinkedIn profile under the line about "great communication skills, mastery of social media platforms—including Twitter."
