Why is Prom happening every single week??

This feature is extremely immersion breaking when you don't even have the option to toggle it off. I play a lot of historical gameplay, so there are times that I don't want prom to exist at all in my world. And the fact that prom shows up for all teens, even if you have them quit school, makes absolutely no sense. 

What's especially irritating is the game doesn't even make it easy to just ignore it. If you don't go through all the motions of agreeing not to go to prom, any potential love interests will develop a bitter sentiment about having expected a prom invite (even if they're a YA and no longer in school themselves!). Why are sims that are neither in school themselves or partnered with another sim who is still getting prom notifications? That makes so little sense that it's jarring in game. 

Please give us the option to disable Prom, or at least cancel it and remove it from the calendar each time the event is generated! Better yet, let us toggle on or off ALL high school events so that if we don't want our sims to participate, they stop clogging up the calendar UI.
