LONDON — A woman who recently found herself without a roof for the night after missing the last train home from London was so inspired by how her evening was transformed by a homeless man that she took to Facebook to share her story.

After spending the day in London, Nicole Sedgebeer missed her last train back to Milton Keynes — leaving her without shelter until the next train the following morning.

She explains on Facebook, that just as she was about to break into tears, she met Mark who told her he would take her to a cafe that was open as it was too dangerous to be outside on her own.

Not only did he find Nicole somewhere safe for the evening, he even returned after leaving to collect his sleeping bag to walk her to the train station the next morning.

"This man who I probably would of avoided eye contact with if he asked for spare change, completely changed such a negative event into the most eye opening event in my life," she wrote on Facebook.

When commended by a friend for her post, Nicole went on to say, that she asked Mark why he did it, and he replied, "it was a father's duty to get another man's daughter home safe."

They also took a photo together, which was Mark's first ever selfie.

Mashable has contacted Nicole for further comment.
