Toilet paper fort

As the virus spread across the globe, so many people are afraid.
And they will pay anything for food and supplies.
I sit here in my castle made of toilet paper rolls, surrounded by a moat of bleach.
I load cans of soup into the catapults, ready to drive off bands of roving hoarders and scavengers.
Should they make it past the moat and into the gate, I will pour gallons of bleach through the murder holes to murder any infections they carry.
Safe and secure in my fort, a thought strikes me…
I wonder who will walk the dog.
