To me, that screams an absurd level of immaturity and disrespect for rules. 

I have heard about immature children ruining their parents credit and doing crimes etc.

Now Person D lives in their apartment and there have been a few disputes however mot of them were handled by the tenants themselves with conversations, I only heard bout them after the fact when another issue came up.So in retrospect, I think in my case A, B, & C were both somewhat "problem" tenants, all were a bit immature and had issues having a direct conversation with a neighbor, somewhat to be expected when renting to college students in their 20's.  

This goes to show that your take on serious matters is immature and can't be taken seriously. 

A lack of wisdom is immaturity.

It's not immaturity on anyone's part.

Further, your overall arrogance and distain for people who invested utilizing different criteria than you is immature, mean spirited, and flat out ignorant.

While I appreciate you taking the time to reply, your response is a bit immature when you do not have a full understanding of the situation.

@Lauren Hogan  It is possible that they wanted to rent the lower unit and are to immature to actually talk to you and this is somehow their solution?

You need to control your immature desires to buy "stuff", before you financially deserve it.
