Dear Black Widow,
Gee golly gosh! Thank you for building your new home right near my dog's food dish! I'm sorry but you have to go. Normally I like spiders, but I've had this vendetta against your species since I was bit when I was 10 when one of your kind decided to bite me in my sleep. That fever and my allergic reaction to my medication was not fun. Nor was the rash on my thigh blowing up like a balloon.
Bye bye,
Rin
P.S. I guess I should thank you for not biting me or my dog. >:(
The spray wasn't working very fast so i went out and killed it with the underside of a dog shampoo bottle.
