Water? I drink alcohol from time to time, used to smoke and drink coffee when I was in high school, I've tried drugs, but I'm not addicted to anything, but I do like water.
Other than that, I suppose I'm addicted to theater, always watching what other people do in their everyday life and archiving that in my memory for later use in building a character or making an everyday action. I also put me in imaginary situations from time to time, like when I was in a bus and I convinced myself that I was in with the person sitting next to me, which was a man.
Oh, and music. Being, talking about it or just listening to it, I love it. Although not all kinds of music, I still think anyone who listens to vallenato should be exiled from earth.
