Simon Harris' awkward encounter with disability worker Charlotte Fallon in Kanturk, Co Cork, on Friday night could be one of those defining moments in this election campaign.
It was a mistake by the Fine Gael leader who ended the interaction abruptly.
Other parties say the incident is indicative of the Government's neglect of those working in the area of disability.
Something which is disputed by the Government parties.
Yes, Mr Harris can point to meeting and greeting hundreds of people cordially everyday, but this is the one that has now been viewed millions of times online.
And that moment in isolation presents an image of a politician who is tetchy and thin-skinned, two things someone seeking votes cannot afford to be.
It is at odds with Mr Harris' typically consistent affable approach.
It is a fact too that improving disability services was the reason Mr Harris entered politics as a teenager.
His colleagues have rallied to his defence, with Paschal Donohoe and Helen McEntee talking about the empathy he had demonstrated over many years.
But what happened in Kanturk suggested there are moments when Mr Harris might lack that vital attribute that every battler needs - the ability to take a punch gracefully.
There was also that curious moment on the Upfront debate last Monday night when he pointed out that he was not the one who signed the contract for the National Children's Hospital where costs are soaring.
Technically true of course, but he was the minister for health who got government to agree to fund the hospital.
He did later say the buck stopped with him, but he did not react calmly in the moment when the heat was on.
All this takes place against the backdrop of a feeling politically that the three major parties are now on a broadly similar level of support as the campaign enters its final days.
The days ahead will be interesting and will likely set the course for Irish politics over next five years.
