Honestly, who schedules a big kickoff project meeting for 5pm on a Friday during lockdown (even if is is easing)? 
Everyone is going to be tired and grumpy - no one is exactly going to be fizzing with enthusiasm and ideas after a long working week.
It’s all on camera, with many different companies represented, so I’m going to have to dress properly, makeup on, all of that...
Of course, I’ll be professional and push through, but I still think it’s rubbish timing.
