There's a concept in psychology called transference. Transference is when you treat someone not as themselves but as someone else from your past. It explains why you associate certain feelings, like familiarity or annoyance, with people you've just met.
Transference is important in psychology because it gives therapists insight into clients' past relationships and potential issues.
Transference is also important in business. It's why employees put their bosses on a pedestal and treat them with a greater amount of veneration than can be rationally explained. They do this because they see the boss not as a person responsible for achieving business results but as, you guessed it, their parent.
This also explains why millennials, who increasingly come from homes with absent or missing parents, don't quite think you're as much of a hotshot as you might think you are.
