Tried to ask my parents, they told me to hide until the feud subsides.
I would hide like a motherforgeter dude.
Seriously.
Get in your room and lock the door.
Do not let anyone in until the cops come.
Seriously. I'm not loving joking.
This never happened to me (and I kinda wish it would, it'd be exciting), but I know the best thing to do is do what your parents say - hide.
