It's like a few months ago when discussing the Napoleon film with my friend, she had previously learned that Napoleon was exiled to an island (twice) and also that he was defeated at Waterloo, so she assumed The Battle of Waterloo was either entirely a naval battle or naval with some aspects on an island. She then said she hasn't watched the film but will eventually because she enjoyed the naval battles in Pirates of the Caribbean so she wants to see Ridley Scott's take on the Battle of Waterloo.

"You... You've conflated two completely unrelated facts about this one subject in your head. Waterloo was not a naval battle"

"He was on an island when he lost?"

"No he was exiled to an isla- wait, did you think Waterloo was on the water because "water" is in the name?"

"He was defeated and died on the island? Was it not a naval battle?"

"Those are two completely different events"
