A friend is doing repairs, asked to install the door to the bathroom.
In the process, they talked: I would like a shower cabin instead of a bathroom, but I am afraid of a closed space.
I was joking:
All phobias come from childhood. Did your parents lock you in a closet for bad behavior?
She thought a little.
It wasn’t closed, but there was a case at the school.
And she told me that they went with the class on a march and in the evening, when she was with her girlfriends in the tent (brezent, the old pattern, it was still in the times of the USSR), classmates cut off the stretches and the tent folded on them. Then the boys walked on the perimeter to the tent and did not let them get out until the teacher came to shout. She said she had forgotten this story for a long time, but then she was very scared.
Of course, she did not get rid of the phobia, but at least she knows the reason.
Thus, seemingly, innocent jokes may appear in the future.
