I'm going to correct my date who thought that ben franklin was a president
What are you going to tell him?
That Benjamin Franklin was an inventor!
It can be frustrating talking to a date when you know they are wrong. Explaining to them that Ben Franklin was an inventor may help educate him for the future.
I love to educate people.
It is understandable to have the urge to correct a glaring flaw or mistake that can be easily corrected. Just don't be condescending or smug about it.
