Jo Cox's children have raised a fear ahead of the one-year anniversary of her murder by a far-right terrorist.
That is, will the 10 million people set to take part in nationwide events acclaiming her life this weekend all be turning up to and cramming around the houseboat in which they live on the Thames?
Jo's widower Brendan says it is six-year-old son Cuillin and daughter Lejla, four, above anything else who have kept him going throughout the past 12 months since much-loved Labour MP Jo was killed in her Yorkshire constituency last dreadful June 17.
But he has also been encouraged and inspired by the response to the 'Great Get Together' events being held across the country today, tomorrow and Sunday – not only celebrating Jo's life but also the very principle of unity over division.
While Brendan plans to spend a little time ahead helping the volunteer relief efforts at Grenfell Tower in west London, he is also intent on attending 'about seven or eight' events this weekend both in London and Jo's home county of Yorkshire.
He insists throwing himself into such a vast project is no mere distraction from grief, but the best way to commemorate and celebrate her lifelong commitments – with the full approval of the two young children in which he sees so much of her reflected back at him.
He said: 'The difficult thing is, you need to avoid doing stuff which is just displacement.
'But because this feels important, it's trying to achieve something significant about bringing our communities together when some people are trying to tear them apart.
'That gives me some comfort, in the sense I'm taking forward Jo's legacy and the issues Jo and I always worked on together all through our lives.
'For me the overwhelming priority has been making sure the kids are okay.
'Because they're okay, they're really strong – they have a lot of Jo's spirit and vitality – that's helped me cope. Without them, I wouldn't have coped.
While Lejla has been assiduously rehearsing a dance for the occasion, Cuillin will play his ukulele – 'badly', his dad nods, 'because he only knows one note'.
But while that may be a parent's privilege, a knowing dig at his own kid, the true pride shines through – even if a few mislaid fears have needed allaying.
'The kids are really looking forward to taking part – they see it as huge.
'I was talking to them the other day about how we're looking at maybe getting 10 million people taking part and they suddenly got very worried.
This weekend will see not only street parties but barbecues and picnics, coffee mornings, tea parties and iftars, all in support and aid of the Jo Cox Foundation and its partner charities.
Sir John Major, Tony Blair, Gordon Brown and David Cameron last night issued statements in support, Michael Gove and Ed Balls have cast aside political rivalries to dance together and comedy sketches have been filmed for Channel 4's The Leg tonight.
Jo herself proved anything but counter-intuitively partisan in her all-too-brief parliamentary career, such as teaming up with Conservative ex-international development secretary Andrew Mitchell to set out a response to the Syria crisis involving humanitarian access zones without flinching from confronting the evils of the Assad regime.
While her pre-Commons career exemplified a commitment to the benefits of international aid, through the likes of Oxfam, so Brendan provided similar not only at Save The Children but also a cogent overseer and analyst of cross-charity campaigns such as the Big IF campaign.
And so, justly, such collaborative instincts continue anew now.
'We went out of our way from the beginning to make sure this wasn't a political event, not only when it comes to parties but also organisations.
'We have everybody from the RSPB to the Countryside Alliance, the TUC to the CBI – very different organisations getting engaged and involved.
'More importantly, it's all different sizes and styles of event, from ones in London with thousands and thousands to a tiny one with just three people on the Orkney Islands.
'The great thing is, people are adapting it to what suits them, because the idea itself is so simple.
'There's been an incredible reaction in terms of people looking at what's happening in the world – what's just happened in west London, for example – and wanting developments that bring us together.
'People do feel fraught about life at the moment.
'We're all supposed to hate each other because of politics or Brexit.
As for what happens come Monday and onwards, he at first aims to get some rest after such a tumultuous year – and recent weeks that have included not only last-minute planning for this weekend but last week's publication of his heartachingly reflective book, Jo Cox: More In Common.
'For me everything's been focused on this weekend but through the Jo Cox Foundation we are going to continue to think about what more we can do to bring communities together, particularly at a time like this when some people are fixating on trying to tear them apart.
'But I'm not quite sure what at the moment.
They can at least keep and enjoy that safe haven, that houseboat, to themselves. For a bit, for now, at least. Before plenty of #MoreInCommon to come.
