US Democratic presidential nominee Hillary Clinton has featured in a candid post on the famous Humans of New York blog.
In the post, Ms Clinton discusses perceptions of her character and recounts a story from her youth of experiencing sexism and learning to measure her emotions.
"I know that I can be perceived as aloof or cold or unemotional," she says. "But I had to learn as a young woman to control my emotions. And that's a hard path to walk."
Ms Clinton writes about being heckled as a young woman while sitting a law school admissions test at Harvard.
"While we're waiting for the exam to start, a group of men began to yell things like: 'You don't need to be here.' And 'There's plenty else you can do.' It turned into a real 'pile on.'
"One of them even said: 'If you take my spot, I'll get drafted, and I'll go to Vietnam, and I'll die.' And they weren't kidding around. It was intense. It got very personal.
"But I couldn't respond. I couldn't afford to get distracted because I didn't want to mess up the test. So I just kept looking down, hoping that the proctor would walk in the room."
Ms Clinton says while she may come across as "walled off", she doesn't view herself as cold or emotional.
"But if that sometimes is the perception I create, then I can't blame people for thinking that."
Ms Clinton appeared on a Humans of New York Facebook post last year, commenting on a photo of a gay teen expressing his fear over discrimination he may experience as he grows up.
"Your future is going to be amazing. You will surprise yourself with what you're capable of and the incredible things you go on to do. Find the people who love and believe in you - there will be lots of them," she wrote.
