I've never heard of normalcy bias.

Thinking much bigger picture, I had an alcoholic binge drinking uncle I worked for as a teen. I often assumed a lot of responsibility for him in his business at times, sometimes for a couple of days at a time over a period of about five years, then stepped back into "normal" once he was sober.

Similarly, I had a parent who drank for blocks of time, maybe regularly for a few months, then would be sober in excess of a year, sometimes two years.

My oldest pointed all that out to me recently. I've always said I have a short memory, and a selective memory where I remember the good times. My wife could verbally shred me one night and I'd chalk it up to a bad night, then hang out and cuddle the next night.

During the good times, I frantically want do my part to secure them and sustain them.
