I think in a sense its a good that Truss was more or less just functional rather than a personality.
It was arguably her big week, but in being wooden / boring / whatever the spotlight falls on the Queen.
She had a big week to deal with WITHOUT the extra burden of having to attend a bunch of unexpected engagments and think about the funeral.
She possibly has had barely any time at all to think about a speech much less write one, unlike Johnson, Starmer, Harman, May - all of whom may well have had something preprepared to an extent. Johnson's speech did make me think he knew her death was very imminent. Truss has had the summer to campaign and put a new team together for no10 and to think of a plan for the cost of living crisis.
To illustrate the point, the privvy council meeting that got cancelled on Wednesday was a swearing in of members of Cabinet to their official roles. Until this is done they are limited to what powers they legally have. The result is that 'work arounds' have had to be found on a functional level, yesterday and today. Instead parliament will be sitting in an extra session tomorrow - a Saturday, in part to allow for this swearing in ahead of the official appointment of the King tomorrow.
The big thing is 'it wasn't about her' and she didn't try to make a witty anecdote. She possibly hasn't had as much contact with the Queen as some of the others. Saying something understated may have been deliberate and indeed wise. It might have backfired if she told a witty story. It might well be inappropriate ahead of her meeting with Charles. Better perhaps to 'shine' more further down the line.
Her job now is to build a relationship with Charles. The two of them need to get on and be able to lean on each other. In this sense, letting her emotions run away ahead of being one of the first to meet the new King is a big deal.
She now has to think about how she will be greeting many of the world's leaders just two weeks into the job. Imagine how daunting that must be to think of in terms of bollocks like getting the ettiquete right and not upsetting various heads of state by getting it wrong. Biden has already indicated he wants to come - its likely its going to be a pretty full house.
Its a moment of huge significance and importance to the UK to use as a opportunity to centre ourselves and ensure that the soft power of the Monarchy continues. Its difficult to overstate this.
Good luck to Liz. She's going to need it over the next couple of weeks. I'm willing to give the benefit of the doubt. Ultimately I want a PM who is serious and boring and actually does policy well not PR and photo ops well.
