It was in the early 90s. I was 3 years old. I went with my parents to my aunt in Ukraine. Late in the evening, they try to persuade me to go to bed, I refuse. Then the uncle says that if I don’t go to sleep, then the babysitter will come. And I said I won’t come, there’s daddy and mom, what I should be afraid of. He left and returned in 5 minutes. Gas in the head. I was terrified by this species incredibly (I did not see anti-gases in my life), the baby came. I could not reassure myself for a long time. As a result, I normally did not sleep as adults. Thank you, Uncle Igor, I still remember.
