During a hostile act the most important thing to do is to remain calm. The wrong move can get you injured or killed.
If possible, you should try to call the police (you don't have to say anything to them, just call). If any emergency officials give you directions, follow them.
-Don't make any sudden moves. (Moving quickly is dangerous in this situation unless directed to do so) -Try to hide (if there is a place to hide, and if it's safe to move). -Remain quiet (to prevent provoking the person who is holding you hostage). -Be cooperative. (This could save your life)
Kyle is definetlyunderweight you can tell even before doing the math. If he is 6 foot and weighs 125 LBS this man needs to see a doctor because he should be atleast 175 which would give him a BMI of 23.7
