Why would she when he was visiting a vaccination centre in First Minister Arlene Foster's own constituency? That was no coincidence.
This shot-in-the-arm for Unionist relations brought obvious side-effects, fuelling Nationalist fears of him further defaulting on the Northern Ireland Brexit deal.
Ms O'Neill accused him of a "reckless and partisan approach" to the Protocol, negotiated to ensure there would be no hard border on this island.
She said the PM had not facilitated a "long-standing request" for a meeting with her and her party leader.

She heard him before she saw him. "Arlene, how are you?" he boomed from the foyer, "Nice to see you again."
It was hard to believe this was the same Boris Johnson her party has accused of "betraying Northern Ireland" with a border in the Irish Sea.
He couldn't have chosen a more symbolic location for this visit. If anywhere understands the danger of Brexit and the Protocol re-opening old wounds, Enniskillen does.

Rightly or wrongly, that implies there could be further unravelling of the agreement he made with the EU.
And that's exactly why Sinn Fein, the Irish government and the EU have lost any faith they had in Boris Johnson.
The question is why are the Democratic Unionists still pinning their hopes on the man who imposed the sea border they despise?
