Mice!

Yes, my house has mice. We caught one this morning in a mousetrap, but we don't know if we have more. Meanwhile, I'm becoming really paranoid. I seem to think there is a mouse in my room, and I'm scared to be too quiet, because if the mouse comes out or makes noise on the assumption that there is nobody awake in the room, I will freak out. And I'm convinced that something inside the walls was keeping me up around 2 A.M. last night, but I may have been dreaming...
We have 2 mousetraps where droppings have appeared, and the exterminator's coming tomorrow. I would really love to be rid of them...
