Good question. I don't know how much of mine is genetic and how much was learned. I didn't realize that 1-3 of my grandparents are/were high-functioning alcoholics (family seems to disagree on this) until the first time my drinking really got me in trouble and my mom started yelling at me about it over the phone. My dad and I have very similar drinking habits, and he is arguably a high-functioning alcoholic. I know he has identified as one in the past. There is a lot of grey area with my family, but I probably inherited some sort of predisposition. I was also a very observant kid. And, of course, I've made my own mistakes along the way.
