A disclaimer, A warning and the start of a story

Its a story about a person I guess
It's also based on a true story, the story of one of my friends who's name I won't mention for the sake of their privacy.
They wanted me to write a story about it cos yeah. most of it is true but some parts that I won't name right now aren't.
Fair warning: it will be quite mature I mean it starts in the eyes of a 7-year-old so it will get worse if I decide to carry on to however old they are.
