You were still a kid. In fact, you were Lawrence and Molly's kid. You knew your parents worked for a government organisation, but that was about it. They never ever spoke about their work nor did they gossip with their colleagues; they would sometimes bring over to the house so you had no idea what they did.
They dropped you off at school as usual, waving you off.
Lawrence: "Bye, me and your mother will pick you up at 4 like usual, alright?"
Molly: "We'll see you then, be careful and study hard!"
They drove off, leaving you to head into school, except today you weren't going to school; you had prepared yourself to follow them as curiosity got the better of you.
You followed their vehicle's route all the way to a government building with fences all around it, managing to somehow sneak your way in, then get into the building behind them. You follow them down the corridor for a short while until you lose them and find yourself lost in the halls of the SCP Foundation without even knowing what kind of dangerous place you are even in.
