A young man from Dublin has touched the hearts of many, after the story of how he saved a man's life went viral.
The Facebook post, which has had nearly 25,000 likes, details how Harrington spotted a man on the brink of suicide and went to speak to him.
By asking three words, "Are you okay?", Harrington saved the man's life - and now he's going to be honoured in the most wonderful way.
"I was just on my way to the American sweet shop to buy some Gatorade, when I saw this guy in his 30s sitting on the ledge of the bridge," explains Harrington.
"I just thought, 'wow...' I stopped and asked him if he was okay, but I knew from the look in his eyes he wasn't, and he didn't say anything either, but I saw tears coming from his eyes."
Harrington pleaded with the man to come and sit on the steps with him, which - after some persuasion - he did.
"We sat on the sidewalk on the south side of the Liffey and talked for about 45 minutes, about what was happening to him, why was he feeling that way," says Harrington.
"I couldn't leave him there alone, but I had to go, so I was going to ring an ambulance. I told him they could help him feel better. But he was like 'please, please don't call them, I'm fine, I just want to walk around for a while, I'm gonna be okay!'
"I told him to please let me ring an ambulance, that I wouldn't sleep knowing he was just walking around alone."
Jamie rang the ambulance and the man was taken to St. James Hospital.
Before he went, the young lad asked for the man's number so he could left him know he was safe.
"About three months ago, he texted me that his wife is pregnant, they're having a boy, and they're naming him after me," said Jamie. "Can you believe that? They're going to name their child after me.
"He said in that moment that I approached him, he was just about to jump, and those few words saved his life.
"That they're still ringing in his head every day. 'Are you okay?'" Incredible.
