factually late
When you say something is a 'fun fact' but it's just something people already know, and you look like a clueless toddler who thinks the sky is green.
'Did you know the Great Wall of China is visible from the moon?' 'That’s not even true, and I’m not even Chinese.'
'You just told me that the sun is a star.' 'It’s a fun fact!' 'I’ve been living under it for 12 years.'
'You told me that Earth is round.' 'It’s a fun fact!' 'I’ve been on it since I was born.'
