OKAYSOLIKE, you can throw up on her and she'll be all "Eww D:".
Or, you can make her throw up. Which wouldn't be a smart idea unless you had a lot of food in your inventory.

Okay, on a side note, What the hell? Why is she bleeding still? I put a bandage on the goddamn wound. Not only that, I soutured it. e-e

If you go into cure, and then x-ray of EVA, you can see her stats. (medical and food history) The medical history is kind of funny. It includes things like broken nails, breast enhancement, a night terror, colds, lower back pain, etc. Then her food history shows all the fancy things she's eaten. It's a lot of fancy things.

You can make her lie down in mud! *gigglesnort* Then she'll be all muddy. Of course, you'll be all muddy, too. :/

On another side note, I'm thinking about getting Rosetta Stone. I was debating between Russian, Japanese, and Chinese. But I'm pretty positive I want to get Russian.

I of course have to save up for it. Rosetta Stone's expensive. Dx

My passion for MGS has spiked again. It happens. If I start playing, I become so absorbed that I can't stop thinking about Snake and Raiden and Meryl and Otacon and Campbell and Big Mama and ..uh... and Liquid and the black guy from the second game who goes like "LA LI LU LE LO!?" and SIGINT and Para-Medic and Naked Snake and THE FURY, THE SORROW, THE FEAR, THE END, THE BOSS, ALL THE OTHER BOSSES, and everybody. Mostly Snake. ;D

And now it's getting out of hand. I looked into how the MGS movie was doing. And I saw they were debating on an actor to play Snake. And then I screamed at my computer screen, "ONLY SNAKE CAN PLAY SNAKE" and I don't mean David Haytor, I mean the actual video game character. xD;
