My sister requested a post about my sister

Srah is my sister. She is an evil mutant from another planet that has somehow managed to convince many people that not only is she human, but that she is a witty and sarcastic 23-year-old graduate student with an entertaining blog. This is not true. In fact she is an evil lizard person, but I guess she can type and create well enough to fool people, so I guess I shouldn't reveal any of her other secrets.
