Unfortunately, this is real world. So, I believe most of the things need permission, right?
Well, some people not care about the permission. If that person do not agree to let that action happens, the other person insist to do that way without permission approved. What will be happened? What do you think?
Mostly, a person no give the permission to someone, but the action was damn right, it should be no problem to let the action happen.
In my past, someone did action on me without my permission. The ending is just like so-so. Well, when I did the action back on him without his permission, what I deserved was a slap. It seems like I have no rights to give permission if he insist...
Permission is important?
