But on a positive note, discovering all these small quirks are like "Achievement unlocked" kind of moments if you like learning languages.
You pronounced the "h" like in "hot"? (with the "h" making actually a sound?). I am quite surprised because we do not pronounce and "h" when it starts a word (usually at least), and I've been learning English in the 80's with Brian and Jenny (kudos to the ones who had the same manual) and it was not taught that way either.
ADDED: You do see a remnant of this with "an historical" but even that is generally not preferred in most dialects. https://www.alphadictionary.com/articles/drgw007.html Basically, it has to do with whether the initial "h" is pronounced in a given dialect of English.
e.g.
Hot Happy House Hotel Humble Hundred Help Hippo

I looked it up on wikipedia and of course it was "The Lord" XD
