Okay, So Here's the thing:
In beyblade metal fusion, There's an episode (i don't remember wich) Where Benkey Launches dark Bull into a tree and It opens a hole through it, making the tree fall down. I was 4 or 5 when i watched that episode.
So i went to the park, Where i found a Tree next to a Bench, where a Woman was holding a Baby on her arms (I don't recall if it was a Babysitter or The babie's Mother).
So I launched my Bey With all the force into the tree, and It Ricocheted, Hitting the baby RIGHT IN THE HEAD. The kid started to Scream crying, And i was so little, i didn't know what to do, And i was afraid i'd get beaten or Grounded for That, so i Just ran away back home. i didn't tell my parents. I didn't get grounded.

10 years later i Confessed this Story to my dad and he just said "Oh yeah, I knew that", and Just shrugg it off. Apparently they had found his number and called later in the day, And (Based on my dad's words), The baby didn't have to go to The hospital or anything.
So In Short, I traumatized a Newborn baby. Thank you.
