It is. I have just checked. Basically all events QMII were to attend have been postponed.
All except of her boarding Dannebrog for the season next week.
I'm not surprised though. I think it has always been doubtful as to what she could manage this side of August.
That Frederik has had to take over the audience, something QMII can sit down to do, does not indicate she is doing well these days.
Her managing the balcony scene on her B-day may have been due to strong painkillers.
At the traditional move of her residence to Fredensborg, she did display an uncharacteristically episode of temper. Something she would otherwise not do, but when it hurts your threshold goes down.
Having problems with your back is no joke. At all! Not for anyone and certainly not for someone aged 83.
It takes time to recover.
What was the temper episode? (I missed that.)
The Queen is probably like everyone else -- you start to feel better, overdo a bit, and set yourself back.
