You gave Rufus quite a fun play day! He's going to need a really juicy, plump mousy!
I have a couple snakes that really have no interest in people, but most of mine appear to like hanging out... they come to the front of the cage, they climb onto my arm of their own free will, they explore my hair and clothes, slithering all around. I call that an interactive personality. The more time they get with their person, the more they engage. That seems like a definition of enjoyment to me.
If snakes only tolerate us and get stressed by all handling, they we shouldn't have them as pets because that would be inherently cruel.
