You start to hear a hissing and scratching as you reach to push that depression, something brushes your leg as you get your finger in the hole and push. Abruptly, *Another click*, and the door swings open, and with the rush of light you look down, and see a snake curled around your leg, aparently startled and is about to strike. You kick your leg so hard a horse would be jealous and the snake goes flying into the wall, and you run for the open door. That was close wasnt it *Grins*
