An alcoholic home is chaotic and unpredictable.
This is something that has a profound effect on the development of children. We see it among abuse survivors, and we see it with kids who grew up in broken homes, and dysfunctional families. (And the fact that there is a lot of crossover in those groups, should tell us something about how kids grow up in these situations and where they will struggle in adulthood.)
I recognize a lot of myself in these.
