SERIOUSLY???

So... I am officially grossed out. I'm not sure if I will be able to sleep tonight. I was sitting here on my make shift bed when I saw not one, but two centipede type creatures scurry across the floor. I don't think they were friends, as they were obviously different species of centipede, but I am sure they are in cahoots! How many more are there, and why are they in my room? My mom's boyfriend says they come in when it's really hot outside, and I say, gross! (Itch, Itch!)
