I found this in /Showerthoughts and /thelittlemermaid. Since reposting isn't allowed here and both conversations are archived, I'll quote a summary of those posts here.

I don't think that Ariel and Eric get married immediately after the final battle. Actually, we don't know how much time passed between the scene of the kiss on the beach and the wedding scene, because there's a time skip, many of some months or even years, so I think Eric or someone else (maybe Carlotta) explained her all that she needed to know about human life during that period.

Specifically, I have a headcanon (set during Ariel and Eric’s engagement period) of Ariel randomly waking up during the night because her brain told her something was wrong, and when she realized she was bleeding and had stomach pains, she panicked and, believing she was about to d!e (when your first period comes, it can be terrifying if no one has explained anything to you beforehand... for example, it happened to my mother), immediately ran to call the first person who came to mind: Eric. She ran to Eric’s room (in the past, an unmarried couple couldn’t sleep together), woke him up, crying in panic that she was about to d!e. Eric was very scared at first, too, but then when he asked her where exactly she was bleeding and if, by any chance, her stomach hurt too, he understood what it was, reassured her by hugging and kissing her, called Carlotta, and they explained it to her together (or maybe, Carlotta kicked Eric out of his own room, because before that, men were not supposed to know anything about her period, because it was seen as a private female thing).

Donald Pleasance "forgot" to take his hat off for nearly an entire days worth of shooting during Halloween 4. They tried to let it go, but it became too distracting.

Everyone on set kept snickering and saying, "Oh my god? Did you see Donalds hat? He looks so fucking stupid I cant breathe."

Things came to a halt when director Dwight H. Little told him he needed to take the hat off.

Donald Pleasance got really upset with the director and was quoted as saying, "I'm putting the hat back on! I don't care what happens to me! Im not taking the fucking hat off!"

Eventually they finally got him to take it off to reshoot. He took the hat off, and he hid his head in his hands. You could tell he was crying. He kept saying under his breath, 'You can't fucking do that.'"

Rumor has it Donald Pleasance also had two dice in his pocket, but was too afraid to show anyone.

Like, are people still in their cars hoping to get through? Just patiently waiting for all that nonsense to end?
