Mayor Pete Buttigieg gives his opinion to eleven years on the intimidation at the end of the campaign in Iowa

At a public meeting in Iowa City, Mayor Pete Buttigieg did more than his usual campaign speech to give an 11-year-old advice on how to deal with bullying. In a gesture against President Trump, Mayor Pete said it was also important that "we have a president who does not show this type of behavior."

Buttigieg drew the question of Rebecca Johanns, an 11-year-old, from an aquarium. Johanns later told ABC News that she had been intimidated and that she wanted to hear from the mayor about how to handle it.

Buttigieg recounted his own experiences of intimidation in front of 600 voters inside a crowded Wildwood Smokehouse & Saloon.

"I had experiences of bullying when I was growing up," Buttigieg said. "The difficult part is that you really want to blow up the balloon and catch the air of this bully."

"You control if this brute turns you into the best part of yourself or the worst part of you," he said.

Buttigieg, the mayor of South Bend, in Indiana, who would be the country's first openly homosexual president when he won, said some of the bullying was the product of bullying.

"The person who intimidates you probably has something a little broken in them," he added. They want an answer from you. "

"When you show that it does not suit you, they will follow your example," he said.

The president is known for giving unflattering nicknames and insulting his opponents, whether at campaign rallies or from his Twitter account.

Johanns said she took care of the bullying as she walked away and noticed that some people were just looking at the story.

She told ABC News that she will now try to follow the mayor's advice.

"I like the way he was so sincere and friendly," said Johanns. "It was so meaningful."
