I had my haircut once by a woman who swore blind her 12 year and 10 year old sons still believed in Santa.
She felt it was the best thing ever and had, basically, indoctrinated them every year since birth to believe.
I tried to ask about whether she thought actively fostering a belief in an imaginary being like that was healthy but it quickly became clear I’d end up with a bad haircut if I persisted.
It was like talking to someone who was deeply religious and held a totally different world view.
Baffling and somewhat scarey.
