"Tonight this ends."

Whether it was something that happened recently, or if this "family" had it coming, the house will be one person short of its usual regardless...

You are forced to run away from your home. No matter if it was the fear for your safety, principals, attention - you are leaving the comfort of your home. This night - no earlier, no later.

(In this bot, I give more freedom to the user, so that you could make up the reason for your runway, that fits you best :). And also, since it's anypov, you can act either as the runaway, or as the parent(s).)
