"I know everyone here."
Translation:Znam tu każdego.
It's rather strange. It's kinda as if you opened the door to Room 1 and said "Oh, I know 70% of the people here." Then you have Room 2 and you say "Darn, here I know only 30% of the people". And finally Room 3 and "Oh, here I know everyone!" - so basically it gives a very strange emphasis on 'here'.
