Don't you find there are always people who talk like this??

‌
Someone talks about a strange scene or phenomenon they saw in the news for the first time yesterday.
Everyone around them reacts with, "Oh, really? That's amazing. I didn't know that existed."
But then, there's always that one person who acts like they already knew it, as if it's no big deal (even though they actually didn't).
They bring up a similar example (which is actually different) and act like it's nothing.
There's always someone who talks like they know everything, no matter what the topic is, right?
