Sometimes I'm afraid of how quickly I can go from tearing up at a movie to thinking about how quick and easy it would be to chopping someone in the windpipe.
I don't let myself be seen doing anything unless I have practiced it until near perfection first.
Not having many friends and moving around 11 times while young forced me to study social interactions- without participating...of course. As a result, I can mimic just about any nuances of personality people have, and spent a long time figuring out my own habits.
In my job, I see very sick people and very sickening people. Sometimes I wish I could take the illnesses of those who suffer silently and give some very sickening folks a taste of what real illness is.
