I'm incredibly impressed that you managed to make that whole message without a single usage of the most frequently used letter, except in your quotations.
Such omission is a hobby of many WWW folk. I can, in fact, think back to finding a community on R*ddit known as "AVoid5", which had this trial as its main point.
I did ask G'mini for synonyms. And to do a cursory count of e's in my post. Just as a 2nd opinion. It found only glyphs with quotation marks around it. It graciously put forward a proxy for that: "the fifth letter".
It's not oft that you run into such alluring confirmation of your point.
My first post took around 6 min & a dictionary. This post took 3. It's a quick skill.
No LLMs. Ctrl+f shows you all your 'e's without switching away from this tab. (And why count it? How many is not important, you can simply look if any occur and that's it)
Down with that foul fifth glyph! Down, I say!
