My patronus would be a spider, because I am small, and very sneaky, and when you first see me I seem innocent but when you turn around I either disappear without you knowing or, if you get on my nerves, bite you in the butt (not literally). I am also not what you seem, I look small but really I can easily kick a fully grown man's butt. (Just like some little spiders can sometimes have deadly venom.)
