I definitely relate. I've never liked alcohol myself and am not in the drinking culture at all. I have almost never recognized when someone is drunk. Many is the time when I question someone's behavior and my husband will point out that the person is drunk. Always comes as a surprise to me.
It took me many years to look back at my childhood and realize that when my stepfather was violent and abusive he had been drinking. At the time, I had no clue at all.
