**** SOMEONE HELP ME NOW?

my dad took my shrooms out of the cabinet that i have them hidden in, he thought they were regular mushrooms so he threw them in the pot with the steak. I refused to eat the mushrooms so i just had steak. my little sister, my grandma, and my dad are all tripping right now. my dad is crying and my sister is hiding under her "invisibility cloak" like in harry potter. its kinda funny in a way, but im pretty sure im screwed when they sober up... how do i make them forget this ever happened?! hurry! EMERGENCY!
