Need a New Apartment....

So, there is a staircase right outside my front door. I use it everyday. More recently I have noticed cracks on the steps that seems to be spreading and getting worse. The first time I saw them, I had a vision of the steps falling off the building with me on them. I talked myself out of that stupid fear. I am for sure the lightest person that uses them, so why should I be worried, right?! But on Friday night I came home and they have closed the stairs. With no explanation, besides the obvious cracks on the stairs. I'm a little frustrated....I do pay rent here...they could at leat write some sort of memo to the residents. I think it is time I look for a new place to live. One that isn't falling down.
