factually late
When you bring up a 'fun fact' and it's so obvious that it feels like you just told someone that water is wet and they're now questioning your intelligence.
'Did you know the Earth goes around the sun?' 'I’ve been going around it since I was five.'
'You told me that fire is hot.' 'It’s a fun fact!' 'I’ve been burned for 10 years.'
'I told my dad that bananas are yellow.' 'I’ve been eating them for 40 years, you idiot.'
