...And I thought everything on this planet was out to kill me.
Once I found it, it wouldn't stop following me. It's very curious about shiny objects and has taken to spinning whenever I am trying to rest. It simply doesn't want to stand still.
It's pushy, but this far away from home I find the company very soothing.
