First of all, the music was on between 7-8 PM on Friday and once you told me to shut it off it was never on again for the entire weekend. Also, your neighbors on Floor 2 were having a large party. Secondly, your extremely aggressive neighbor who stormed the apartment violently after being angry that no one was answering the buzzer (which you told me not to do) wanted us to send the elevator down (which was not even on the floor nor did I know or care to know how to operate as again you mentioned to never use it). Next, you should have notified anyone with a key to not enter without knocking. I am unsure if that is regular practice but it did not make me feel any safer, especially after your violent neighbor's diatribe, violent pounding of the door, excessive language and forcing himself into the entry way.
