One of the highlights of the the final night of the Democratic National Convention was the speech given by Brayden Harrington, a 13-year-old boy with a stutter.

Brayden met Joe Biden in February in New Hampshire, while the former vice president was on the campaign trail.

“About a few months ago I met him in New Hampshire he told me that we were members of the same club. We stutter,” he said in his speech on Thursday night. “It was really amazing to hear that someone like me became vice president.”

Biden invited Brayden backstage after his speech in New Hampshire to talk about how he has worked to overcome his stutter, and showed the 13-year-old his speech on paper, where he had marked when to take breaks between words.

“He told me about a book of poems by Yeats he would read out loud to practice. He showed me how he marked his addresses to make them easier to say out loud, so I did the same thing today,” Harrington said, flipping the paper in his hands around to show the camera his speech.

“I’m just a regular kid, and in a short amount of time Joe Biden made me more confident about something that’s bothered me my whole life,” said Harrington. “Joe Biden cared. Imagine what he could do for all of us.”

In a campaign speech in February, Biden revealed the lengths that he has gone to in order to control his stutter. He mentioned that his mother’s support helped him overcome his struggle, saying that she told him, “Joey, don’t let this define you. Joey, remember who you are. Joey, you can do it.”

“So every time I would walk out, she would reinforce me,” he said. “I know that sounds silly, but it really matters.”

Biden said he stays in contact with about 15 people who he has met with stutters and has told them  it’s “critically important for them not to judge themselves by their speech – not let that define them.”
