This made me think of a sister or a bitchy friend who likes to walk all over you and use up all your stuff. It was kind of funny in a way, or maybe I'm just over tired. Roaches are funny right now, I have one in my house almost as big as my chihuahua. Anyway, nice write!
I think you've done a very good job of showing us the vindictive nature of the narrator. This is well-crafted, the way it builds from low-level annoyance to declaring all-out war. Frankly, I'm not "into" such a negative message, but it's well done for the genre. I think it's a waste of time getting mad at people. It's a big wide world, & let's just move on. I'm hoping all your writing is not steeped in this dark blood.
