Most of the focus on preparing for Brexit has so far centred upon business, as needs be.
But just as EU membership was about more than the movement of goods, being outside the EU will have consequences for people as well as for trade.
As the transition period ends Brexit will begin to have a real impact.
That impact will be a little different here in Northern Ireland compared to the rest of the UK, and not just because of the Protocol.
For starters, most people born in Northern Ireland have a birthright to claim Irish citizenship.
This means that many of us will still have that means of accessing freedom of movement, i.e. the right to live, work and study in an EU country.
