1.) I am able to subtlety push on emotions, change peoples minds, or give them a general direction. Not exactly mind control, but still. I also blend in. I don't become invisible, I just blend in the the background.
2.) Stubbornness. If somebody does not listen to my quiet voice, then their stubbornness hurts me and I have to pull away. I can be killed like normal people too.
3.) Static
4.) I use my power to begin arguments, because I enjoy fights and things. I can rob things, and stay in the shadows.
(I'm sort of like a soother or rioter from Mistborn)
