A person who will talk about facts until everyone is tired, even if they’re completely wrong and don’t know what they’re talking about.
They spent 30 minutes explaining why the sun is yellow and then got mad when I said it’s actually white.
They told me about the first fact they ever learned and still haven’t stopped talking about it.
They got into a fight with a teacher over the number of letters in the alphabet and lost because they thought it was 30.
