The worst one definitely is when my skull got opened after i fell on the stairs with 6 years old. Well, not me, but my dad who was carrying me and i was sleeping since we had just came back from traveling to my uncles house, my dad could hold himself on a wood bar, not the same for my case. They had to take me urgently to the hospital where i got 6 surgical sutures. So whenever i cut my hair, in the back of my head there's a "C".
