YOU DONT NEED ANYONE'S PERMISSION TO TAKE BACK SOMETHING YOU OWN. Its not stealing when you own it.
Are you the kid that's in the lunch room who opens his lunch box and the kids at the table take all your food and eats it in front of you and you do nothing about it? Are you going to ask permission to get your peanut butter and jelly sandwich your mom made for you? Or are you going to be the kid that snatches that sandwich back from the bully (even if you get the sh*t kicked out of you) at least you stood up for yourself and not get taken advantage of again??
