It could be Eat but Idk A lot So Go with your gut
Fire drills and earthquake drills also have an emergency number like 911 and closest family members phone number
There is a number of things you could do you but the best thing you could do is to leave the situation and go get help. You should avoid getting into it because that could just make it worse same goes with being defensive. I hope this helps!
