The key concept they’re missing a lot of the time is that software sits within the file system and not the other way around.
This is largely because apps hide this and data is generally stored in one place on your phone (the downloads folder).
Best way to fix it - have 1–2 lessons entirely devoted to finding shit on their computer. My favourite activity is “ok, save your word file, close word, you now have 10 mins to find that file without opening word”.
Let me offer a scenario; two drunk people who wouldn’t normally go near each other spend a night together. The morning comes, regret is in the air for both parties, which of these two people is most at risk?
The correct answer is: “the one who doesn’t accuse the other on social media”.
Just remember, no-one gave any indication of gender there. It’s not really about gender at this point - it’s the fact we’ve constructed a world where a casual encounter has the potential to become the prisoner’s dilemma if it is regretted afterwards.
That’s not a world where people take risks on a date, especially if physical intimacy is on the cards. To much risk!
