This young lad is having a happy birthday and is all excited to blow out the candles on his cake. However he never gets that opportunity thanks to some meddling douche.
While bowing down to make his birthday wishes and blow out the candles, someone behind him shoves his face into the cake. Does the instigating shitbag realize that they just shoved a young child’s eyes into a cake with flaming candles? The birthday boy takes exception and promptly throws the entire cake at the crowd behind him because everyone is guilty by association. He then grabs a slice of cake and hurls it like it was grenade.
He then runs away crying with his birthday and childhood ruined.
And that folks is how serial killers are made.
