it kinda depends on the time and where my girl is at. at night she cruises around in her cage like nobody else's business. she'll be all over. when she's out of the cage she be exploring like nuts. but usually during the day, she's hiding (that would be the nocturnal aspect of her).
it may be that your snake feels comfortable being out. it probably understands that nothing will happen if it comes out of hiding. kind of like getting over a fear or something. i dunno. just a thought.
