I must be honest here. As a former biology teacher, I have handled my share of disgusting and creepy creatures, and I am not much of a sissy girl, but I have also done the chair thing at the sight of a scurrying mouse.
I shared a dorm room and apartment with a 10 foot boa constrictor, have assisted in surgery (animal), am not afraid of large animals, but will shriek like a little girl if a mouse comes near me. However, I would never call the police or seek counseling.
