Answer:
I destroy your home from the inside out.
I canβt go left I canβt go right. I am forever stuck in a building over three stories high.
I do not contain flesh feather or scales; yet I have fingers and thumbs.
I run around the city but I never move.
I make you weak at the worst of all times. I keep you safe, I keep you fine. I make your hands sweat and your heart grow cold. I visit the weak, but seldom the bold. What am I?
What always comes into the house through the keyhole?
