Foreigners are flying into the UK from various countries around the world to pay their respects.
Think you'll also find people around the world like to queue up for hours for even trivial things such as Black Fridays. Remember the mad scenes of folks grabbing other peoples things?
People around the world did mad things during the pandemic too.
Human Beings have ALWAYS been weird and irrational. It's not new.
Why don't you concern yourself with what you're doing today instead of obsessing about what others are doing in paying their respects to the Queen?! 🤦♂️
