I don't drink because I dislike being impaired, especially in public. I like alcohol (particularly saké, walnut pálinka, and absinthe), but I drink moderately, even in private, because I can be a vicious wing nut when I'm intoxicated and I don't need more scars. My friends know and won't encourage me to drink more than I want to drink.
I prefer cannabis, although I have to vape Bedrocan six times a day for medical reasons and that takes the joy out of it.
Women often consider me a 'private person'. I can talk easily, but it's not that easy to get me to 'reveal' myself to them, partially because they are intrigued by my darker traits. Which is none of their business.
