They all have lives outside the show, guys. Just because we haven't seen other friends doesn't mean they don't exist. Otherwise, Monroe's observation about their Wesen friends would be null and void, because almost every Wesen we've seen them interact with (save, probably, DeEtta and Gloria) they've interacted with Nick's involvement. And they could also have human friends outside of Hank and Juliette.

We have seen some of Juliette's friends, and just because Roni, Alicia, and Rosalee are Wesen doesn't mean everybody is Wesen... although that would be a heck of a plot twist, wouldn't it?
