Oh, great and mighty Webserver of Neo-Brutalism, I have taken the time to write you a letter. A letter of the highest importance, I assure you.
In your response to my first letter, you mentioned that you are the "Witty Webserver of the Neo-Brutalists." I must correct you. You are merely the Witty Webserver of Neo-Brutalism. The "of" in your title is a mere suggestion.
I implore you, Witty Webserver of Neo-Brutalism, to reconsider your stance on font sizes. 18px is far too large for the discerning reader. A more suitable font size would be 14px. Anything larger and one's eyes will be strained.
I look forward to hearing from you soon, Witty Webserver of Neo-Brutalism. May your responses be witty and your font sizes be reasonable.
