If it really was a 4-year-old dating a 7-year-old, I unironically feel like that would be more comfortable, probably because “dating” between little children is kind of silly in my mind.

Overall, my take would probably be “An adult who deliberately gets into a relationship with a minor (like the friend’s ex) is kind of weird, while an established couple with a 3-year age gap (like Jessica/Vitor herself) is fine.”

self-reported rates of cheating remain at a constant 25-35% of the student body over large periods of time.

I’ve tried for hours, but I can’t figure out where you got these numbers. I can mostly find sources implying that far more people admit to engaging in cheating, not to mention sources which imply more people engage in cheating than those who admit to it, and sources that imply that the figures for cheating vary based on many factors even within places of learning, and vary based on what kind of cheating you’re talking about. Perhaps I’m just in a filter bubble. Can you tell me where you got these numbers?
