Noting a correction is part of a larger scope of annotating something. From Wikipedia:

There is also a two-thousand-year-old character used by Aristarchus of Samothrace called the asteriskos, ※, which he used when proofreading Homeric poetry to mark lines that were duplicated. Origen is known to have also used the asteriskos to mark missing Hebrew lines from his Hexapla. The asterisk evolved in shape over time, but its meaning as a symbol used to correct defects remained.

In the Middle Ages, the asterisk was used to emphasize a particular part of text, often linking those parts of the text to a marginal comment. However, an asterisk was not always used.

Aristarchus of Samothrace was from c. 220 – c. 143 BC, so it’s been used for notation since at least then!

Do you think this cat is leading a double life? They’re raking in twice the treats and food!

Close! Mrs Robinson is the name of the song and the older woman in the movie. While the younger man is being seduced by the older woman (who happened to be a married family friend), her daughter who is around his age catches his eye.

Just spitballing an idea. Along the lines of airdrop, does the instructor have a machine that the kids can send their music to when they’re done? This would create a backup, which the instructor could then organize and upload to a server (google drive?) that can be shared with the iPads as read only, so the kids could redownload the file again if need be.

Would its impact create a solar flare? And if that flare was hurtling towards Earth, would it be more devastating than other solar storms we normally see?

There’s a lot of references to this, but it looks like there’s not a known source. Interestingly, the first reference to this tablet was from 1908. https://quoteinvestigator.com/2012/10/22/world-end/

What was the common thread from when you met the person? How did you hit it off with them?

If you met at a bar, text them later asking if they’ve been to a certain brewery that just opened up (although this could sound like a soft invite to go there, so be prepared for that). If you connected about movies, tv shows, or music, ask them if they saw that new movie (show, album) that’s related to whatever you talked about (same director, sense of humor, style of movie, etc). Basically, just continue the conversation with them. Talk about related things and start to branch out, maybe you’ll find other common interests and things to talk about. You can send an article that you think they’d be interested in. Or a meme about their job.

But make sure that the conversation isn’t one sided. If you’re always the one starting the conversation or carrying it, maybe back off some. They should be just as engaged as you are.
