My grey is afraid of loud noises. If she's out on her play stand and I drop something in the house, she jumps off and takes a lap around the house and lands on the ground. She's leery of me walking near her play stand while carrying any large object -- a freshly washed blanket folded up, an economy-sized package of toilet paper, etc. My house isn't huge, so I have to walk pass her play stand when I'm putting away laundry, supplies, etc. I always make it a point to tell her, "It's OK," beforehand, but she gives me A LOOK and leans her body in the opposite direction as I go by.
