You’re right. I think Delta became more “insufferable” toward the end when the author didn’t know what to do with her, so, from being cool headed and mature she turned into sanctimonious, holier than thou and putting down Luann for her goofyness. That’s why she didn’t appear in the story after high-school.
Delta was the insufferable one in High School, but Benice had to take her place as someone who would endlessly lecture Luann. It’s just the way to do it that is different.
That’s a common practice. And search “Fat Free Water”, you’ll be surprised that bottles of drinking water with such a claim on the label do exist, as ridiculous as it sounds. And burgers have a lot of sugar in them, that’s one of the main health problems of fast food so, a sugar-free burger would have to be a special burger, it can’t be a selling point on normal burgers.
I went ZX Spectrum, Commodore 64, Apple IIe, Atari 1040ST. The Apple was the most expensive of the lot. The Atari was truly a revolution (mouse, windows style OS, like Macintosh but more affordable).
Reminds me of Homer about to give a kidney to his father: he thought they grow back. A man of science should inform Luann that she has only a limited number of kidneys. She can only give 5 or 6, after that it’s over.
Especially when it is named Gort.
