A Statistics teacher in Gotham makes a graph comparing times when Bruce Wayne goes on long vacations with times Batman gets beaten up really badly by villains to illustrate to his class how correlation does not equal causation.
Imagine Dick Greyson as a uni student in that lecture, loosing his goddamn mind.
The students come to the conclusion that Bruce Wayne goes on vacation specifically to beat Batman up.
Actually, if I were in that class and not in the know and wanted to find a causative link, I’d have it the other way around. Batman gets hurt, so Bruce Wayne - whose galas and parties regularly get attacked by supervillains that Batman always seems to wind up saving him from - decides to lolnope out of Gotham until the resident superpowered-loony asskicker is back in form.
