Wikipedia diving

My brain must be running on fumes or something.

I saw the news about the Epstein royal, and the prince being all >:( about it now that everybody is talking about it and his royal ass can't pretend he knows nothing about it.

So I went on Wikipedia on the page for the Charles guy.

Then on the page for Lizzie.

Then on the page for longest reigning monarchs (she being the 2nd longest).

Then on the page for Queen Victoria (why did they name a queen based on an Underground line??).
I read a whole bunch of that page.

Then, reading about Scotland in there, I searched for home rule.

Then went on the page for Faroe Islands.

Then on the British occupation of Faroe Islands in WW2.

Then on Overstamp. Because the Danish money was overstamped.

Then on Postage due.

And that's how I found out that there used to be dedicated stamps for when the sender didn't pay enough (to then ask for the rest from the recipient).

Then I got curious about Germany and Germany never had stamps dedicated for that. But they still have the system.

If you write your sender address but don't put enough stamps on the envelope, they put a yellow sticker that implies "bruh who taught you maths?" and bring it back to you (without invalidating the stamps you already put there so you can just add the difference and send again).

But, if there's no sender address, then they put a fancy blue triangle and NE on the letter and then charge the recipient the remaining amount + 70 cents if they want to receive the letter.

And now my brain fumes are going "well having an envelope with that triangle on it sounds cool".

This is one of the rare instances in which I can completely describe a chain of Wikipedia digging.
And what the fuck.
How did I get from royal buddy buddy with Epstein to feeling like giving Deutsche Post a 70 cent (- VAT) donation?

And all of this at between 3 and 4 in the morning.
