I love black tea, particularly Earl Grey. I find it very comforting, like a warm hug. Starting in fall I drink several cups a day. During the summer I make iced tea.
Green tea shouldn’t really be strong, you’re probably steeping it too long. I drink green tea if I’m after something light (or if I’m out of milk, which I need for black tea).
Imo there was no reason at all. I’m Canadian and I had the UK version. I figured things out just fine and if I couldn’t, I asked!
I once tried to download the ebooks but accidentally got the US version. It absolutely ruined the immersion, and the arbitrary word replacements seemed to get lazier and lazier further into the series.
