My NT blackheaded python is fairly un-interested with my business, He's always awake and semi-active during the day, but he's by no means interesting until I try to pick him up.. My Tiger jungle is more interesting, although she is not at all keen on being handled, or people coming too close to the enclosure.. She has a tendency to strike at the glass etc if you go sticky beaking!
8mm thick glass on her enclosure!
the lizards (I have 3, 1 central beardie, 1 eastern beardie, 1 NT frill neck) are all relatively friendly and tame, all continiously active and inquisitive during the day, all seem to enjoy being handled, and love time out of their enclosures... I find snakes grow very attached to their enclosures after they've been fed in there a few times... once they are attached, they tend to protect their personal space, and definitely are not keen on coming out.. (jungle is more adverse than the black head, although the black head throws a bit of a hissy fit when you first open his enclosure..)
