Okay, here's the part I don't understand: "Let's" has an apostrophe, but "permits" and "makes" do not. Why is that? What makes people choose to add apostrophes to some words but not others? Clearly it isn't *all* words that end with an "S," but I don't understand how the decision is made. I thought maybe it was only for verbs, but there isn't one on "makes." A lot of times, they will get added when making a word plural, but that isn't the case here at all. Even more confusing is that most browsers will highlight mistakes with little colored squiggly lines, and most phones will automatically remove the fuckup, forcing you to back up and force-accept the fuckup. Both ways, the mistake has to be consciously accepted, making it more effort than not doing it wrong. So what is the thinking then? Are apostrophes only used on words with a certain number of letters? Or only words containing certain letters? I really am confused about this, and am trying to understand the reasoning that drives the decision to consciously add punctuation marks to words that would never them normally.
