Bunnies as judges of character?

So far I have found that my bunnies are friendliest to the visitors I like and trust the most, and inattentive to (or even hiding from) people I have reservations about*. I wonder if they pick something up from me, or if they are judging people in some way of their own and coming to similar conclusions.

* Don't worry, I don't let really awful or dangerous people in my house! But everyone has some friends and family members they would be able to rely on more than others.

I would think they are picking up on your feelings if anything

Mine hide from everyone - all my friends think they are totally boring as they never do anything intresting or entertaining when we have visitors.

If bunnies are good judges of character, maybe I need some new friends!
