Knowing Everyone

"My other friend, Katie, lives in the same state as you. Do you know her?”

FYI: Yes. I know every single person (whether their name is Katie or not) in every single state or country I have lived in and currently live in.

If you know a Hans (but you forgot his last name or the city he's from) in Germany I know him too. If you know an Olga (you think was once from Russia) I know her too.
