Chill yes, but that's how boas get us to let down our guard.When I had a BCI, one time I had her out for "exercise" & she laid still on my bed while I was folding clothes. Not a hint of her intention to sneak off, but the one & only time I left the room for a couple minutes, she slithered off & hid in a partly-open
bureau drawer. And hissed up a storm when I found her hiding place. It was adorable, really...she didn't want to part with "her" drawer.
