As March 29th came and went, the BBC's special correspondent Lucy Manning, attending yesterday's Leave protests outside Parliament, put it well:
Lucy Manning: They wanted it, voted for it, won it, but didn't get it.
And Laura K put it pretty well too:
Sophie Raworth: Let's go back to Laura. We had been expecting to stand here and be counting down to 11 o'clock tonight, when the UK officially left the European Union. That hasn't happened. Who knows when it will happen? It really is quite a moment.
Laura Kuenssberg: It is Sophie.
And, of course, for Theresa May it was a promise that she made to the public, time and time and time again: "We will leave the European Union on the 29th of March".
That process that she triggered was something then that Parliament itself voted for.
And of course at the General Election not so long ago, in the long history of Britain's tangled relationships with the EU, both of the main parties committed to leaving, and then in Parliament a huge majority of MPs voted for this to happen.
And at the very least, wherever blame lies, whoever made all of the different miscalculations, the fact is that Parliament has not been able to deliver to the country something that itself promised would happen.
